P
Pacemaker	1  A model name used by Wahl-Eversharp in 1938 (below, upper) for a mid-line lever-filling pen. The Pacemaker shared its Art Deco design sense and some specific design elements with the Coronet, introduced two years previously.  2  A model name used by David Kahn, Inc., for a gold-nibbed World War II-era Wearever button filler that was the top of the company’s line (below, lower). See also Coronet, Kahn, Wahl-Eversharp.
Packard	A brand used on cheap, poorly made syringe- and lever-filling pens produced in the 1930s and early 1940s by a now-unknown manufacturer. Packard pens had untipped steel nibs (imprinted DURIUM or DURIUM TIPPED) and were not designed to be repaired. It is not unlikely that this name was chosen to suggest a relationship with Packard automobiles; the prospective purchaser might infer therefrom that the pens were of high quality, as were the cars. See also DURIUM.
packing	(also packing unit) The seal around the plunger shaft in plunger-filling pens (such as Sheaffer’s Vacuum-Fil) or the retracting shaft in retractable safety pens (such as Moore’s Non-Leakable). Usually made of cork or felt.
paktong	Anglicization of the Cantonese phrase 白銅 (baak tung, “white copper”). For definition, see nickel silver.
palladium	A strongly tarnish-resistant silver-white metal (atomic number 46) of the platinum group, used in pens as plating on nibs and, because of its relative hardness, as a component in some tipping alloys. See also palladium silver, tipping material.
palladium silver	(abbreviated PdAg) A class of tarnish-resistant silver-colored binary alloys of palladium and silver. Developed in Germany by Heraeus in 1931, palladium silver was used to manufacture nibs from the 1940s to the 1970s as a less costly alternative to gold. As with gold, a higher silver content (up to about 40%, at which point tarnish resistance begins to suffer) yields a softer alloy. See also palladium, silver.
Palmer	Austin Norman Palmer, born in 1857, inventor of the Palmer Method of handwriting. When Palmer was a young man, the standards for handwriting were Spencerian and other similar ornamented round-hand styles that required careful control with the fingers to produce the desired thick and thin strokes with a flexible nib. Palmer reasoned that for business in an increasingly rapid environment, a simplified style that did not stress the writer would be more effective. His Palmer Method taught muscular writing, in which the hand and fingers cradle the pen in a grip that barely suffices to keep it under control while the upper arm muscles provided the movement. Flex was not a part of the Palmer method; all strokes were of uniform weight. Beginning in 1904, well after parochial schools began teaching it, Palmer’s method began to achieve recognition in public schools, and it soon became widespread. Palmer founded the A. N. Palmer Company, in Cedar Rapids, Iowa, to manufacture and sell books teaching his method as well as pens designed for it. Palmer Method fountain pens offered a choice of medium, fine, and extra-fine semiflexible nibs and were priced well under $1.00 in wholesale lots for purchase by schools. Palmer died in 1927, but his company (which moved to New York City in 1955) is still in business today. See also calligraphy, copperplate, round hand, Spencerian, Zanerian.
palm shellac	Term for a mixture of rosin and castor oil, used as a sealant and adhesive for certain joints in fountain pens, most notably by Sheaffer to install “TRIUMPH” points into pens. Palm shellac contains no actual shellac, and it does not soften as easily as true shellac. See also shellac, varnish.
Pansy	A decorative engraving style featuring pansy blossoms, used on vintage overlay pens; deeply incised and similar in appearance to the type of work frequently seen on decorated firearms. Shown here are a full-overlay Waterman’s Ideal Nº 05521/2V Pansy Panel and a portion of the Pansy overlay on a Moore’s Non-Leakable Safety Pen. (Pansy Panel alternates engraved and plain rectangular areas around the circumference of the pen.)
Parco	A bottom-line model produced by Parker for a short time beginning in 1933. The Parco appeared in a button-filling version similar to the Challenger, which appeared in 1934, and a lever filler that was the antecedent of the Parkette, which premièred in 1934. The Parco was inexpensively made; but the button-filling version was fitted, even at its low price, with gold-filled furniture. See also Parkette.
Parker	(G. S. Parker Pen Company)A pen manufacturing company located in Janesville, Wisconsin. Founded in 1888 by George S. Parker, a teacher of telegraphy. Parker sold John Holland pens to his students and then, when the pens failed, learned to repair them. He founded his company with the goal of producing a better pen. A string of patents, of which the Lucky Curve feed, the washer clip, and the Parker “51” are a few of the major highlights, has kept Parker at the forefront of the industry since its founding. Headquartered today in France, the company still produces excellent pens, perhaps the best known of which is the resurrected Duofold (shown below). See also Duofold, “51”, first tier, Lucky Curve, Vacumatic, washer clip.
Parkette	The model name that Parker applied to its bottom-of-the-line lever-filling pens. In the middle and late 1930s, the company produced a Parkette (shown below, upper) and a Parkette Deluxe (illustrated at fluted); the Parkette name reappeared in 1950 on a hooded-nib model (below, lower) intended to compete with Scripto, Webster, Eclipse, and other third-tier hooded-nib models. See also Parco, Zephyr.
Park Row	See Eclipse.
Pastel	(also Petite) A small Parker pen model introduced in 1926. Offered in two sizes, the Pastel came either with a clip or as a ringtop, and its delicate solid colors befitted its name. In 1927, Parker added a series of moiré colors to the Pastel range; shown below is a smaller-size Pastel in Coral Moiré. See also moiré.
Patrician	A pen model introduced in 1929 by L. E. Waterman. The Patrician was the top of Waterman’s line, but it never achieved the widespread popularity it probably deserved because in the same year Sheaffer introduced the Balance, whose torpedo shape made the Patrician's Art Deco styling appear old fashioned. The Patrician shown below is in Moss-Agate, one of Waterman’s most attractive colors. See also Balance, Lady Patricia.
Patriot	A pen model produced during World War II by Morrison. The Patriot was made in several versions to commemorate each of America’s military branches: Army, Navy, Army Air Forces, and Marine Corps. A syringe filler, it was marketed to civilians, with the suggestion that it would make an excellent gift for their relatives in the service. Shown here is an Army Patriot pen-and-pencil set, which was priced at $7.50 (including $1.25 excise tax). Read a profile of the Patriot here. See also Cameo Top, Morrison, syringe.
Paul Wirt	See Wirt.
PdAg	See palladium silver.
Pearce	(F. T. Pearce & Company) A jewelry manufacturer located in Providence, Rhode Island; founded in 1879 when Frank Thomas Pearce, senior partner in the manufacturing firm of Pearce & Hoagland, bought out his partner. Pearce’s firm also made gold pens (dip nibs) and pencil specialties, and, beginning within a few years of 1895, fountain pens. In 1907, the company was reorganized as the F. T. Peace Company, Inc., with Pearce as president and his son, Aldridge Gardiner Pearce, as treasurer. Both Pearces died in 1913; the next year saw the company reorganized, with D. M. Wall as president and general manager, and J. J. Laney as secretary and treasurer.
pearl	Colloquial shortening of pearlescent: having a translucent, iridescent appearance like that of pearls or, more particularly, mother-of-pearl. Usually refers to whitish or off-white colors. See also mother-of-pearl, Pearltex.
Pearl and Black	(also Black and Pearl)  1  A color offered by Parker on Duofold pens (c. 1930) and by a few other makers such as Morrison, featuring black “rivers” flowing over a pale pearlescent celluloid as shown here (near right); catalogued by Parker as Moderne Black and Pearl.  2  (also Nacre) A color offered by Sheaffer on Flat-Top and Balance pens (c. 1924-1934) and by other makers such as Chilton, Wahl-Eversharp, and Waterman, featuring somewhat blocky black and pearlescent areas (far right). Waterman referred to this color as Nacre.
Pearltex	The Carter Ink Company’s name for the lovely pearlescent colors it used on some of the pens it manufactured during the late 1920s. See also pearl.
Peerless	1  (Peerless Fountain Pen & Pencil Company, Inc.) A pen company located in New York City; probably founded c. 1944, the company lasted at least until 1961, when it was the subject of a court order requiring it to mark its pencils clearly as to country of origin. (This order suggests that the company was jobbing pencils; it may also have done so with at least some of its pens.) Peerless pens were of fair quality, using cheaply plated furniture (as shown by the pen illustrated below); but they featured 14K nibs. The company stood behind them with a “GUARANTEED FOR ALWAYS!” warranty, according to a 1947 advertisement.  2  A brand or model name (the PEERLESS FOUNTAIN PEN) used by Cross during the latter half of the 1880s. See also Cross.
peg	See nipple.
Pelikan	(Pelikan Vertriebsgesellschaft mbH & Co. KG) A pen manufacturing company located in Hannover, Germany; founded in 1838 by Carl Hornemann, a chemist, to produce inks, dyes, pigments, etc. In 1863, Günther Wagner joined the company as a chemist and as plant manager; in 1871 he took over the company. In 1878, he registered his family crest, which contains a pelican, as the company logo (shown to the right). In 1925, Pelikan purchased the rights to the piston filling system patented two years earlier by Hungarian engineer Theodor Kovàcs (U.S. Patent Nº 1,706,616, issued in 1928). In 1927, the company hired Kovàcs and Carola Bako to perfect the system for production use, and in 1929 Pelikan introduced its first fountain pen. This introductory pen had no model identification, but the company soon dubbed it the 100 to differentiate it from future models. Shown below are a mid-1930s 100 and a 2009 M400. See also piston.
Penanink	See Waterman, L. E..
Penco	A “house brand” of fountain pens produced by a now-unknown manufacturer for the J. C. Penney Company.
Pencraft	(Pencraft Company) A pen manufacturing company located in Minneapolis, Minnesota and, at one time, in Libertyville, Illinois; founded by George M. Kraker. See also Kraker, Liberty (definition 2).
pen holder	See holder.
penman	1  A highly skilled user of pens, usually one who is expert at ornamented handwriting styles such as Spencerian or Zanerian.  2  When capitalized (Penman), the Penman Company, located in Chicago, Illinois; a division of the United Advertising Company, also located in Chicago. In business c. 1935-1943, Penman was a jobber of third-tier pens manufactured for it by the Starr Pen Company, selling them by mail order. Shown below is typical prewar Penman button filler. In 1942, in response to an acute wartime shortage of fountain pens, the company stopped selling pens at retail; thereafter it wholesaled to jobbers all of its own stock and whatever other pens it could purchase until Starr’s supply of pens ran out in early 1943. At that point, Penman turned over to Starr all the orders it had remaining.  3  When capitalized (Penman), Parker’s trademarked name for its line of highly saturated premium inks formulated and made by Dokumental in Germany and introduced in 1993. Penman inks contained metallic dyes to create their brilliant colors, and they were notorious for staining and clogging. Parker withdrew the line in 2001.
Pennant	1  A model name used by David Kahn, Inc., for a 1950s lever-filling Wearever “dollar pen” that had a tipped, unplated steel nib decorated by a narrow gold-plated bar of steel resembling an overfeed (U.S. Patent Nº D158,973). The cap, made of plastic, was fitted with an aluminum overlay; and the feed was clear injection-molded plastic. Virtually ubiquitous at the time, the $1.95 Pennant (shown below) was produced in greater quantity than any other Wearever model. See also Kahn.  2  The magazine of the Pen Collectors of America.
Penselpen	Schnell’s name for its combination fountain pen/mechanical pencil, a concept not invented by Schnell but successfully marketed by the company in 1929. The Penselpen uses Schnell’s ingenious “shift” (slide) filler. Shown here is an example with the famous “Airplane” clip (designed to commemorate Lindbergh’s 1927 transatlantic flight). See also combo, Schnell.
pen wiper	A small piece of fabric (often felt), frequently home made and decorated with hand work, made for cleaning dip and fountain pen nibs. One account recalls schoolboys using 1936 “Alf Landon for President” sunflower-motif campaign buttons, which were made of felt, as pen wipers.
Permanite	The name Parker gave to the DuPont celluloid used in Parker’s pens beginning with the Duofold in 1926. See also Celluloid.
Personal-Point	Wahl-Eversharp’s name for the interchangeable nib system, introduced in 1929 and produced into the 1930s, that it used in its top-line pens. The illustration here shows a Doric’s section and screw-out nib unit (with an adjustable nib). See also Fineline, Renew-Point, Select-O-Point.
Peter Pan	1  Salz Brothers’ name for its series of midget eyedropper- or lever-filling pens (approximately 3" capped). Introduced in the 1920s as a hard rubber pen, the Peter Pan continued in production, making the transition to celluloid, through the 1930s. Shown below are an early BHR eyedropper-filling pen and a lever-filling pen from about 1939. See also Bantam, midget.  2  A common misnomer for tiny pens in general.
Petite	See Pastel.
petrify	See ossify.
PF	Usually, piston filler. When referring to vintage U.S.-made pens, often means plunger filler. View descriptions and filling instructions here.
PFM	(“Pen For Men”) A pen model made by Sheaffer beginning in 1959; it introduced Sheaffer’s unique Inlaid Nib™ and is considered by some collectors to be the last of the classic pens preceding the era of the ballpoint’s dominance. Shown here is a PFM V. Read a profile of the PFM here. See also Inlaid Nib™.
phenol	Any of a class of weakly acidic organic compounds containing one or more hydroxyl (-OH) groups; the most common has the formula C6H5OH. Phenol is an effective fungicide, acting as a protoplasmic poison, and was used for this purpose in ink until prohibited by law. (It is also toxic to forms of life other than fungi and is regulated as a Class B poison.) Phenol has a sweet, tar-like odor that is readily detected in inks containing it. See also fungicide.
phone dialer	See telephone dialer.
Pick	(Pick Pen Company) A pen manufacturing company located in Cincinnati, Ohio. Incorporated in 1920 by Arthur Schoenberger, the company (named for Schoenberger’s cousin Ed Pick) may have been operating for several years before that date. Schoenberger knew nothing about fountain pens or pen manufacture and hired a former employee of Weidlich to set up his factory. The company remained in business into the early 1930s, finally folding due to its inability to assemble and retain an experienced sales staff. Pick produced pens of very high quality (example shown below), marketing the product to dealers by driving a pen into a block of balsa wood, removing it, and showing that it still wrote well.
pink gold	See rose gold.
Pioneer	See Kahn.
piston	A type of filling system; uses a screw-driven piston. A knob at the end of the barrel drives a long-pitch screw shaft on which rides a piston. In some piston fillers, the knob is also threaded so that it “unscrews” slightly as the piston goes toward the nib and returns to its rest position as the piston is drawn back. This is the “differential” system (sometimes called “double action”), shown here; patented in 1923 by Hungarian engineer Theodor Kovàcs (U.S. Patent Nº 1,706,616, issued in 1928) and introduced in 1929 by Pelikan. In other versions, the knob is fixed so that it can turn but does not travel lengthwise as the piston moves (“single action”). View filling instructions here.
Pitman	A phonetic shorthand writing system for stenographers, devised by Sir Isaac Pitman and first published in 1837. Pitman shorthand is written with an extra-fine flexible nib; it uses thick or thin strokes to signify different sounds. Several major manufacturers advertised their extra-fine flexible nibs as being suitable for Pitman shorthand. Esterbrook produced both tipped and untipped Pitman nibs in its Renew-Point system, numbering them n128. Illustrated below is the first sentence of the Universal Declaration of Human Rights: “All human beings are born free and equal in dignity and rights,” in the Pitman New Era system. (Idealized example provided by Pierre Savoie.) See also Gregg.
pitting	The development of craters, or pits, in metal due to corrosion. In pens, pitting most often occurs in steel nibs; stainless steel is not actually 100% proof against corrosion, and highly acidic inks can attack it. The steel nib shown below illustrates pitting in several places, most seriously in the slit and at the spot indicated by the arrow, where the metal is so thin that the tine bends as if it were made of aluminum foil. See also corrosion, stainless steel.
plain	(also Plain) Undecorated. Used by Waterman and others to describe pens, usually all metal or with overlays, that were not decorated with “filigree” (cutwork), engraving, or other artistic embellishments. The Waterman’s ideal Nº 5521/2 shown here illustrates a plain solid 14K gold overlay.
planned obsolescence	See Dynamic Obsolescence.
plastic	An all-purpose label applied indiscriminately to acrylics, cellulosics, styrenes, and other synthetic resins. See also ABS, acrylic, Celluloid, polystyrene, resin.
plated	Finished by the application of a very thin metal coating, usually by electrodeposition. The clips, bands, and other metal trim parts of most modern pens are electroplated with such metals as chromium, rhodium, or 23K gold. See also gold filled, vermeil.
Plathenium	An alloy of platinum and ruthenium, usually with trace amounts of one or more other platinum-group metals; probably the first of the modern highly refined nib tipping materials (used initially by Parker in 1943). See also platinum, ruthenium, tipping material.
platinum	A strongly corrosion-resistant gray-white metal (atomic number 78), used in pens as plating on two-tone nibs and as an alloying component in some tipping alloys. See also tipping material.
Plexiglas	A registered trademark of Rohm & Haas for its acrylic resin products. Now owned by Arkema, Inc. See also acrylic.
Pli-Glass	Parker’s name for the material of which the ribbed semitransparent sac used in the company’s Aero-metric filling system is made. See also Aero-metric.
plunger	1  A term commonly applied to Sheaffer’s Vacuum-Fil filling system (WWII-era Balance Vigilant illustrated below).    2  The actuator in a Parker Vacumatic-filling pen (1940s plastic version illustrated at right). View descriptions and filling instructions here.
pneumatic	A type of filling system; operates by pneumatic ink-sac compression. There are three variations of Chilton’s pneumatic system. In the first version (illustrated here), the barrel slides on an airtight seal over an aluminum tube that is fixed to the section. A small hole is at the back end of the barrel. When the barrel is extended, the hole covered, and the barrel returned to its rest position, air is allowed into the barrel through the hole and then compressed, squeezing the sac. When the hole is uncovered, the trapped air is released and the sac draws in ink by resuming its normal shape. In the second version, the barrel is fixed and the aluminum tube slides back and forth within the barrel. A blind cap is attached to the tube to give the user a suitable “knob” to operate. The third version resembles the second but has no hole in the blind cap. Instead, a valve opens and closes a concealed air passage. The third version was not successful because the valve proved unreliable. (Sheaffer solved this problem with its Touchdown filler, introduced in 1949.) View filling instructions here.
Pockette	(full name: Kimberly Pockette) A long/short ballpoint pen introduced by Eversharp in about 1947. Shaped much like Sheaffer’s clipless wartime Tuckaway and produced in many colors and trim variations, the Pockette (shown below in a mid-line trim) is very compact closed but posts long enough to be eminently usable. Read a profile of the Kimberly Pockette here. See also Kimberly, long/short, Tuckaway.
Poenaru	Petrache Poenaru (1799-1875), Romanian mathematician, physicist, engineer, inventor, teacher, politician, agronomist, and zoo-technologist; credited as the inventor of the first workable fountain pen (French Patent Nº 3208, issued May 25, 1827). Poenaru’s pen was designed to avoid scratching the paper as steel pens commonly did, it was said not to leak, and it was built from replaceable parts (including either ink cartridges or interchangeable ink-filled barrels).
point	The tip of the nib. Sometimes used as a synonym for the nib as a whole.
point section	See gripping section.
Pollock	(Pollock Pen Company, Inc.) A pen manufacturing company located in Boston, Massachusetts; founded in 1921 to manufacture Robert T. Pollock’s cartridge-filling fountain pen (U.S. Patent Nº 1,658,940), which was called the John Hancock Cartridge Pen. Directors of the company were King C. Gillette, Louis K. Liggett, Henry G. Lapham, Daniel W. Gurneet, Frank L. Belknap, Robert S. Potter, and Pollock himself, with Pollock as company president. The company’s stock was still being traded as late as 1931, but it is not clear what kinds of pens Pollock was selling at that time. The pen screwed apart at a joint marked with a colored ring, near the distal end of the barrel to accept a tubular full-length cartridge made of thin copper and fitted with a sealed threaded opening at its proximal end. The distal end of the feed broke the seal when the cartridge was screwed into the pen. Shown here are a John Hancock pen and a cartridge case with two unused cartridges.
polystyrene	A class of injection-moldable thermoplastic resins of which pens are made, polymers of the monomer styrene, (C6H5CH=CH), which is an oily liquid. Polystyrene plastics came into use as a pen material in the early 1940s; but the earliest formulations suffered problems such as a tendency to shrink or to crumble with age. Much better formulations appeared before the end of the 1940s. Some polystyrenes used in the 1950s and 1960s, notably those in the Parker “21” and 61 and in Sheaffer’s PFM, are brittle and must be handled with care during repair of the pen. Today the most common materials for the manufacture of low-priced pens are ABS (acrylonitrile-butadiene-styrene) and SAN (styrene-acrylonitrile), with polystyrene being used for very cheap products. Better pens are usually machined of acrylic. See also ABS, acrylic, Forticel, SAN, thermoplastic, thermosetting.
Popular Doric	Wahl-Eversharp‘s name for the design of its lower-priced Doric pens, featuring an Art Deco cap band with solid diamonds in rectangular cutouts (shown below). See also Doric.
post	1  (when capitalized, Post Fountain Pen Company) A pen manufacturing company located in New York City. Founded c. 1894 to manufacture pens using a syringe-type filling system (U.S. Patent Nº 510,145) invented by the Rev. Woodruff Post. Beginning in about 1903, Post appears to have been owned by the Reliance Trading Company, a commercial enterprise established by the Salvation Army in that year; but whether it had been founded initially under the auspices of the Salvation Army is not clear. (According to his obituary in the June 28, 1906, issue of The Christian Advocate, Post himself was a very religious man; and among those participating in his funeral services was the Ensign of the Salvation Army at Olean, New York, where Post had resided.) The Post name reappeared in advertising by about 1911. According to Trow’s New York Copartnership and Corporation Directory, the company’s name was discontinued in 1915; but the Post Fountain Pen Company is listed in reference indexes as being in operation, still at its original address, as late as 1921. ¶ The Post pen was very popular, and it was claimed that even Britain’s King Edward VII used one. Post fillers faded in popularity during the 1920s; but during World War II, restrictions on the use of rubber revived the design, and today the system is seen most frequently in crude form on cheap wartime pens. The basic design could be elaborated in quite sophisticated ways, as by the Franklin Pen Company. View a description of a syringe filler and filling instructions here. See also Franklin, Reliance, syringe.  2  To “park” the cap onto the back end of the barrel while writing, as a convenient storage location or to make the pen more comfortable to use. Some users prefer to post their pens because they like the longer shape or because they prefer having the weight farther back. Also (of the pen itself), to have the cap so placed. Some pens do not post well if at all, and some pens that post reasonably well also expose their caps to the risk of cracks at the lip due to the stress of being pressed down onto a tapered barrel. The Parker “51” (illustrated here, upper), with its gently tapered barrel and metal cap with a clutch spring, posts very well. Sheaffer’s Balance (lower) is notorious for cap-lip cracks because of its steeper barrel taper and relatively thin celluloid cap lip.  3  To enter figures in a ledger, as in accounting. Accounting nibs are commonly used for posting and are sometimes referred to as posting nibs. See also accounting nib.
Postal	(Postal Pen Company) A pen manufacturing company located in New York City. Founded in 1925 by G. N. Robinson, V. Buhr, E. Pape, and J. Gerdis, Postal sold a flat-top pen called the Postal Reservoir Pen (in two sizes, for men and women), fitting it with a clear celluloid barrel and a bulb filler (whence the term “Postal filler”). It should be noted that Postal did not invent the bulb filler; the basic concept was patented in 1903 by George W. Perks and Frederick C. Thacker (U.S. Patent Nº 723,726). Huston Taylor patented an improved design in 1905 (U.S. Patent Nº 802,668) and assigned his patent to Aikin Lambert. Postal actually used Taylor’s design, for which the patent had expired. ¶ Selling its high-quality $2.50 pens (illustrated below) only by mail order, Postal operated a clever “send no money now” marketing system that looks like, but was not, a pyramid scheme. With his pen, the purchaser received five post cards to send to friends. By mailing in one of these post cards, its recipient could buy his pen for $2.00. If all five of a given purchaser's cards were returned, that person got his pen free. Postal also produced pens under the Bonded and Transco brands for sale at retail. All of these pens are today relatively uncommon. Read a profile of the Postal Pen here. See also filler.
posting	See ACCOUNT.
posting ring	A ring around the back portion of a pen’s barrel, caused by pressure and wear from posting the cap. See the illustration below.
pounce	A claylike powder designed to be applied to unsized paper before the paper is written on. Rubbed gently into the paper, pounce helps to seal the porous surface; this makes the paper smoother and improves the appearance of the written text by retarding absorption of the ink. Pounce can also be sprinkled on written text to absorb excess ink, but a blotter is usually more convenient. Pounce had fallen out of general use by the early 19th century; today it is most commonly used by artists and technical illustrators.
Precious Resin	Montblanc’s name for the material of which it makes pen bodies. According to Brad Torelli, a pen maker and plastics expert, the material is a relatively ordinary acrylic resin that is manufactured as pellets and is made into pen parts by injection molding. It retains its bright polish exceptionally well but is somewhat brittle due to the lighter molecular weight of moldable acrylic relative to cast acrylic and to stresses created by the molding process. See also resin.
pregnant	Term for a pen with bulges caused by pressure from the inside, most commonly at the pivot point of the lever (from the snap ring that secures the lever in place) or on the underside of the distal end of the barrel (from the short end of a J-bar pressure bar). Pregnancy occurs most frequently in low-priced plastic pens, and exposure to heat accelerates its development. Shown below is the barrel of a pregnant Stratford; note the outward distortion in the area of the lever slot. See also pressure bar, snap ring.
Pregnant Parker	Collectors’ nickname for the now-rare Parker Nº 47 eyedropper-filling pen, whose pearl barrel overlay has a bulbous shape as shown in the photo below. See also abalone, alternating pearl, mother-of-pearl.
Premier	1  A low-priced pen model produced by Parker Canada from 1932 to 1934, one of the models known as a group to collectors as Thrift Time pens. The Premier (shown below, upper) was the Canadian equivalent to the U.S.-made Duette Sr. See also Duette (definition 2), Moderne (definition 2), Thrift Time.  2  Beginning in 1938, Sheaffer’s name for its oversize Balance model. See Sheaffer names.  3  A pen model produced by Parker from 1983 to 1992. Based on the 75, the Premier was longer and heavier, and it featured some remarkably attractive finishes such as the Athenès shown below (lower).
Presidential	Parker’s name for any of its pen models when fitted with a solid gold cap and barrel, first applied to an Aero-metric “51”.
pressure bar	(also, especially in early usage, presser bar) A metal strip, sometimes with formed channels on its long edges, sometimes made of springy metal or attached to a spring, whose purpose is to squeeze the sac in a pen that uses a sac-based filling system. Some pressure bars are formed in the shape of the letter J and are called J-bars. Illustrated here are a button-filler pressure bar from a Parker Duofold Junior and a J-bar from a lever-filling Esterbrook J. See also filler.
prime	(more correctly, priming) The ink that remains in the nib slit while the pen is not in use. A pen that loses prime is one that allows this ink to drain out of the nib when it is in a nib-upward position, and such a pen will not write until it is reprimed by being held nib downward so that ink flows back into the nib. Shaking can accelerate repriming, but — especially with vintage pens and their more primitive feeds — can cause the pen to throw blots.
Prince	(Prince Pen Company) A pen manufacturing company located in New York City; founded by Newell A. Prince c. 1855, with Thomas G. Stearns as manager and agent to the public. Prince’s Protean Fountain Pen (U.S. Patents Nos 12,301 and 13,995) was among the earliest relatively successful fountain pens. The pen filled by means of a syringe-type plunger, antedating Woodruff Post’s design by some 40 years. The later of the two patents listed here shows the plunger shaft with a threaded end so that it could be unscrewed from the head, rendering the pen suitable for carrying in a pocket.
propel	See mechanical pencil.
Protean	See Prince.
pull filler	See syringe.
pump	A filling system that requires multiple strokes to fill the pen, such as Parker’s Vacumatic. View descriptions and filling instructions here.
Pyralin	A trade name for a particular celluloid formulation; used by Wahl and Esterbrook for the material employed in their pens beginning in 1929 and 1932, respectively. See also Celluloid.
pyroxylin	(also collodion) A solution of cellulose nitrate in diethyl ether or acetone, sometimes with the addition of various alcohols; used in wound dressing and as a photographic emulsion in the 19th-century wet-plate process. Pyroxylin is toxic and explosively flammable. As the solvent evaporates, the substance dries to a celluloid-like film.
