We are closing the shop through the July 4th holiday weekend for some time at home with the family -- summer in New England! We will resume order shipment next week. Thank you for your patience.

We offer only a limited selection of parts. The main reason is simple: most vintage pen parts aren't interchangeable. They exhibit a maddening range of variations, and often as not even a correct original part must be hand-fitted. In most cases, it takes as much time to figure out what a do-it-yourself pen repairer actually needs as it would take to do the job ourselves, so please don't take it amiss when we ask you not to inquire about pen parts other than those listed.

Please make certain that the part you are ordering is the one you need -- returns of parts will not be accepted unless defective or not as described. This also applies to renewable components, such as sacs and seals, as well as pencil lead, erasers, and the like.

Unless otherwise noted, all parts are factory-made originals (this does not apply to sacs and seals, where factory originals would be age-hardened and unusable). If unused, they will be labelled "NOS" (new old stock); otherwise, condition will be used but sound. As noted above, some hand-fitting of parts may be required, and nibs (even new old stock) may need some tweaking in order to give the exact ink flow and "feel" on paper that you prefer. Prices listed below do NOT include shipping and insurance; if you wish to buy more than one of an item, quantities can be adjusted within the shopping cart before checkout.

Items without an order button (or quoted but not listed) may be added to your shopping cart through the form below.

Tools & Accessories

A nib block is an essential tool for straightening nibs that are sprung or otherwise damaged. Vintage examples are nearly impossible to find, however, and the modern tool steel blocks that have been lovingly machined and hand-finished cost hundreds of dollars, if you can get in on a one of their limited production runs. Some years ago, we bought a group of old nib blocks from a long-established pen repair service in England. Most were tool steel in various shapes, but a couple were made of acrylic. Though they had some superficial scuffing and scratches from decades of hard use, they were still as good as ever, which inspired us to use the same material for a new run of nib blocks, affordable for every pen hobbyist.

In many respects, acrylic is an ideal material for a nib block. While in some cases a completely unyielding metal surface is to be preferred, more often the slightest degree of "give" is better when bent metal is to be counter-bent to restore it to straightness (we often put a strip of thin paper over our steel nib blocks for just this reason). We have decided not to sell straightening tools for use with these blocks, given that they are widely available at very modest cost from other sellers. For around $5 one can purchase a burnisher as used by jewelers and engravers, or a set of dapping punches with polished rounded steel heads. Making one's own tools is another option: we have several made from cheap screwdrivers that have been cut short, ground round, and polished smooth.

Our new blocks measure 11.5 cm x 5 cm (4.5 x 2 inches), with diameters on both convex and concave surfaces running from 3 to 15 mm (1/8" to 19/32") -- a range that should accommodate nibs of all sizes, from the smallest miniatures to oversize dip pen nibs. Note that these blocks are cast, not machined, and that the convex ridge has a saddleback curve in the middle rather than being dead straight across the top.

$25 each (photos above show the block from each side)


These 5-inch (12.7 cm) nib smoothing disks aren't cheap, but they are the best! The industrial diamond coating strongly resists being scraped off the extra-tough mylar backing -- one can even run the edges of these disks between a nib's tines to smooth the inside edges of the tipping material. Can be used wet or dry, will outlast other polishing media many times over -- a single disk should easily be good for smoothing dozens of nibs.

Available with particle size of either 0.1 micron (ultrafine, for smoothest finish work; dark green) or 1.5 micron (very fine, offers faster deburring; light green). $12 per disk.

NOTE: These are much finer than mylar-backed abrasives sold for hobby use, while the grit size is far more closely controlled. This chart gives rough equivalencies between difference abrasives scales, listing abrasives of up to 0.5 micron as equivalent to 100,000 mesh (our finer grade is, of course, five times finer yet).

SPECIAL PURCHASE: We now have 0.5 micron sheets of the same quality and specifications in 3 inch by 6 inch rectangles (7.6 x 15.2 cm). These are only a bit over 8% smaller in area than our 5-inch disks, but thanks to a lucky buy we can sell them at half the price -- only $6 per sheet.


Cleanout bulbs are essential for pen restoration and maintenance: use them to flush out accumulated ink deposits and sediments from sections, feeds, and nibs, or to clean out dried ink from Parker 61 capillary reservoir units. Similar bulbs were furnished by Waterman for routine cleaning of their eyedropper-filling pens at the beginning of the 20th century. Cheaper, less risky, and often more effective than an ultrasonic cleaner! These sturdy, thick-walled rubber bulbs will last for years. The large bulbs will fit the section nipples of most pens, as well as Parker 51 and 61 nib openings. The small bulbs will fit slender pens and miniatures, such as Eversharp Bantams and Peter Pans. We also now have extra-large bulbs (not shown) with the same opening size as the large bulbs, but twice the capacity. $4 each.

Test tube brushes are another must-have. This set includes one large, one small: the first is a good general purpose brush for caps and most barrels; the second is ideal for the narrow barrels of eyedropper-fillers, and for cleaning out sections after feed removal. Two brushes, one price: $6


Long-necked applicator, a superior filler for eyedropper-filling pens (the long, thin tube reaches further into the barrel, filling it more neatly):
$0.50 each, ten for $2.50


Do you have an eyedropper-filling pen in the box, complete with eyedropper? Chances are, the eyedropper's bulb has long since hardened and shattered. These latex bulbs make accurate replacements, at only $0.60 each.


Pencil Lead

Click here for more information on lead sizes for older pencils

Thick 1.1 mm lead for older mechanical pencils (interchangeable with leads nominally designated as .046", 1.18 mm, and 1.2 mm), as well as .9 mm (.036") lead in various grades and colors. These are fresh production from Autopoint. Each tube contains 12 leads, each 1 3/8" long (3.5 cm). Black lead is $2 per tube; colored lead is $2.50.

Lead Size and Grade Quantity
1.1 mm black B (soft)
1.1 mm black HB (medium)
1.1 mm black H (hard)
1.1 mm red B (soft)
1.1 mm blue B (soft)
1.1 mm green B (soft)
.9 mm black HB (medium)
.9 mm black H (hard)
.9 mm red B (soft)
.9 mm blue B (soft)
.9 mm green B (soft)

VS (1.5 mm) lead, one of the most commonly-used sizes for 19th-century mechanical pencils but long out of production and very tough to find.
Five 2 cm pieces for $6


M (1.05 mm) was one of the other lead sizes most commonly used in 19th-century mechanical pencils, and now virtually impossible to find. Our true 1.0 mm lead will fit M nozzles, albeit a bit loosely. A thin coat of shellac will bring the lead right up to 1.05 mm, or it can be rubbed with beeswax to hold it in place. Another approach is to give the nozzle tip a slight squeeze for a snug fit. Note that current-production pencil lead sold as 1.0mm is actually 0.9mm.
Five 6 cm pieces for $5

Replacement barrels for 1930s Pelikan 100 piston-fillers, newly-made in USA from transparent acrylic (NOT Pelikan production). Finish machined, can be polished internally and externally for additional transparency. Barrel sleeve (binde) fit is deliberately designed to be on the loose side, so as to minimize risk of splitting a vintage binde.

Barrels can be used with or without barrel sleeves, but note that there will be a slight step where the barrel abuts the filler unit if no sleeve is mounted. Make your own customized demonstrator!
$50 each. Colorless clear is only color available (green, blue, and red are now sold out).



Replacement flat coil springs for Sheaffer Snorkel pens. The originals are prone to rust, especially if there is any leakage into the barrel interior from a failed sac or point seal. Even if the rust is removed, there is almost always residual pitting, and a Snorkel mechanism will not retract and extend smoothly if the spring is at all rough. Not original Sheaffer production, but newly manufactured to original specifications, 3 for $18 ORDER or 100 for $300 ORDER

Replacement coil springs for Sheaffer PFM fountain pens. Not original Sheaffer production, but newly manufactured to original specifications, 3 springs for $15 ORDER or $150 for 50 springs ORDER
