OTHERWISE MINT CONDITION


Recently a friend brought a fountain pen to me that needed repair, explaining that he had purchased it at an antique shop which claimed that it was in original, working condition. Being a novice collector, my friend took the dealer's word and purchased the pen at what he thought to be a high price. 

Upon filling, my friend discovered that the pen held very little ink. Understandably, he was frustrated. Upon attempting to return the pen, the dealer quickly pointed to a sign indicating that no refunds were allowed. This is how the pen made it into my hands for repair. 

I soon discovered that the pen, a sterling Waterman 452, presented even more problems. Both the lever and clip were nickel rather than original sterling, and haphazardly replaced at that. The barrel was also a replacement with the numbers on the bottom filed off to disguise its inauthenticity. The nib was missing its iridium, and the sac, though still elastic, was poorly fitted - otherwise the pen was mint. It was this horror scenario that impelled me to alert the budding collector to the perils of purchasing a vintage fountain pen from an antique shop, flea market, or even from an experienced pen dealer. 

When pen hunting, it's advisable to bring along a flashlight and a small magnifying glass or loupe to aid in detecting flaws. 

THE CONDITION OF THE CAP
Cracks in cap: Cracks commonly develop in the lip of the cap and where the clip is attached. To check for cracks in the cap lip, gently rub your fingernail inside the cap along the lip. Visually, with a magnifying glass, check for cracks in the clip area. 
Clip Condition: Gently wiggle the clip to determine if it is securely affixed. Does the pen have the correct clip? With riveted clips it is sometimes easy to determine if a clip has been replaced because the rivets have been poorly fashioned. (With sterling or solid gold pens, nickel and gold-filled clips are commonly used as replacements, but are not authentic.) 
Cap Band Rings: Are rings missing from the cap? Make a thorough check. 
Interior of cap: With a flashlight, look into the cap to determine if the threads have been altered. It is not uncommon to chance upon cap threads that have been treated with tape or crazy glue and cellophane in an attempt to remedy thread slippage. When examining a pen gently check to determine that the inner cap is in place. Note: eyedropper pens have no inner cap.
Filed down cap lips: Sometimes cap lips have been filed down to remove slight cracks or chips. If this has been done, it might be impossible to detect. Check for file marks on the cap lip and try to determine if the wall of the cap lip is too thick.

THE CONDITION OF THE BARREL
Cracks in threads: Cracks can be, easily camouflaged in threads by filing with various kinds of glue. It is common practice to conceal cracks or chips near the top of the barrel threads by filing them down. In this event, the threads appear to end abruptly, or if filled poorly, gaps will be noticeable where the section meets the barrel. 
Warping: Determine warping visually or by rolling the barrel on a flat surface. 
Filed down engraving: Frequently, engraved monograms of names have been filed away or sanded down, leaving a flat surface on the barrel. Take a good look at the barrel or turn the barrel in your fingers to feel for any flat spots. 

SECTION CONDITION
Cracks: A hairline crack in the section is perhaps one of the most overlooked flaws by even experienced collectors. Though a crack may be difficult to detect, it readily becomes evident once the pen is filled. I've failed to notice such cracks on several occasions and have paid for it with messy fingers. 
Missing or broken sac nipples: This common malady can cause great frustration. The only manner in which to determine whether or not the section is damaged under the surface of the barrel is to remove it. However, some dealers might not take too kindly to this, so be careful. Note: if you have little or no experience with pen repair, you may break the pen in the process - so beware.

BACK TO TOP

NIB CONDITION
Missing iridium: Quite often the nib is missing its iridium - either it's broken off, or has worn away with use. Using a loupe or magnifying glass, check the condition of the irdidium. Sometimes a nib that has lost its iridium has been smoothed down on a whetstone for use, so check this as well. 
Cracks in nibs: Cracks frequently develop in nibs. This usually occurs at the base of the nib and are sometimes visible near the section. A good look with a loupe should determine whether or not the nib is intact. Sometimes the nib has been deliberately pushed deeply into the section to conceal cracks. Be wary of this since it is a favorite technique of the unscrupulous seller. 
Bent nibs: This is easy enough to recognize, but a nib that has been straightened might be difficult to spot immediately. Again, make good use of your loupe and check for any scratches, bends, or dings, especially near the point of the nib. If the nib is stained with ink, moisten your fingers and rub away any residue in order to get a good look at it. 

LEVER CONDITION
Waterman: This type employs a lever which is housed in a frame or box which is held in place by tangs within a slot in the barrel. Frequently the tangs of the lever box break. Check to see if the lever box has been glued into the slot to make the pen operable. 

The Waterman filling system utilizes a pressure bar which deflates the inner sac when forced down by the lever. Sometimes the pressure bar has been replaced by a simple "J" shaped spring bar. Many pens which have sophisticated lever/pressure bar mechanisms suffer from being repaired in such a manner. Check for incorrect pressure bar replacement by lifting the lever to the open position and peering in with your flashlight. 

Quality fountain pens, with some exceptions, utilize advanced lever mechanisms. These include Waterman, Wahl-Eversharp, Sheaffer, Swan and late Conklin. 

The above-mentioned pen companies, except Sheaffer, utilize a pin and track lever mechanism. At the end of the lever are two horizontal pins of tangs which fit into a track in the pressure bar. Occasionally, these pins break or are corroded by ink. Instead of replacing the lever, which can be a difficult repair, a spring bar is sometimes inserted as a simple remedy. Obviously, this is not an authentic repair using original parts. 

Frozen lever: If a pen is found with a frozen lever, it is usually because the sac is petrified. Do not force the lever! First remove the sac. A petrified sac is a sure sign that the pen has not been repaired or tampered with for sometime. 
Cracked Lever Box: A common, but serious, problem occurs when the lever is forced open against a petrified sac. The lever box cracks in the middle where the pin holds the lever in place - its weakest point. If the cracks go completely through the box, the only solution is to replace it. Superficial cracks will not immediately prevent the pen from functioning, but eventually they will split the box through continued use. 

Again, you may use a loupe or glass to examine the lever box where the pin is inserted to check for cracks.

OVERLAYS
Much can go wrong with an overlay pen. Because the overlay covers a large surface of the pen, it is possible to conceal many flaws. 

First, check to see if the clip and lever are correct. Sterling overlays should have sterling levers and clips. The same holds true for solid gold levers and clips. Gold-filled overlays have gold-filled fittings. On sterling pens the clip is marked "sterling" and usually appears above the uppermost rivet or under the "Ideal globe" if a Waterman. On solid gold Waterman pens, I have only noticed the "14k" to appear above the uppermost rivet. With Waterman, the lever is marked on the underside of the Ideal globe. Note: marking placement may vary from company to company. 

Barrel repair or replacement: At the last pen show I noticed many Waterman overlays that had replaced barrels. An authentic Waterman overlay should have at least three numbers stamped on the bottom of the barrel. However, early eyedropper pens may have only been marked with two numbers, eg. 12, 14, etc. A sterling pen would bear the numbers "452." The "4" denotes that the pen is sterling. The "5" indicates that the pen is self-filling and has a lever. The "2" represents the smallest standard nib size - 4,5,6,7,and 8 would represent progressively larger nibs. 

A solid gold pen would also have three numbers, but the first number would be a "5" indicating that the pen is 14 karat. Gold-filled pens have four numbers, the first two being "05" indicating that the pen is 18 karat gold filled. 

If the overlay pen has all the correct numbers, then you're in good shape so far. Be alert and scrutinize the pen further. It is not uncommon for an un scrupulous repairperson to alter the numbers. Another tactic is to replace the barrel with an incorrect one and file off the numbers. 

Waterman's lever box covering. Under Ideal globe of the lever should be a thin piece of metal that was designed to cover the tang of the lever box. This covering was designed for cosmetic purposes; however, if it is missing, this is a sur sign that the lever has been tampered with or replaced. It is possible that some pens left the factory without the covering or were repaired by Waterman which opted to leave it off. 

A word about all overlays. On gold-filled overlays, check for plating wear. This is known as brassing because when the thin gold plating or filling wears away, the base metal, which is usually brass, shows though. When a brassed pen is polished, the brass layer is indistinguishable from the gold. To check for this, use your loupe to detect fine lines in the metal. In some cases the brassing will be quite perceptible.

PISTON FILLERS AND VACUMATICS
The blow test: In the event that water is not available to test the filling systems of such pens as Montblanc, Pelikan, Conklin Nozac, and Parker Vacumatics, simply blow into the pen from the nib and section to determine if it holds air. If air escapes through the other end of the barrel, it needs repair. Repairing these pens is complicated and requires special tools, parts and skills. 

The blow test is not a foolproof test, but it will give some indication whether the filling mechanism is functional. Of course, be sure the pen has no ink in it prior to appying the blow test. 

MISMATCHES
Mottled, woodgrain, ripple: What collector hasn't, on one occasion or another, purchased what he or she thought to be a matched mottled, woodgrain, or ripple pen, only to discover that either the barrel or the cap is a mismatch. Study the difference between the various swirled colored hard rubber patterns to be able to spot mismatches of this sort. 
Replacement parts: If a pen has had a barrel or cap replaced with original parts, it is possible to determine whether the match is a good one. Check the wear on the barrel resulting from the removal and replacement of the cap. This wear is noticeable below the barrel threads and where the caps fits on the end. If the lip of the cap does not coincide with the wear marks, then there is a good chance that the cap or barrel is a replacement. Also, if the lip of the cap has been filed down to remove cracks or chip, the cap will not align with the worn area. 

PARKER DUOFOLDS
Nib and feed: Quite often a Parker Duofold is found with a factory replaced nib and feed that are not original Duofold components. When Parker discontinued the Duofold line and ran out of original replacement parts, it was common practice to replace Duofold nibs and feeds with their Vacumatic counterparts. A Vac nib has an arrow engraved on it, and the feed has comb-like teeth. Although the advanced Vacumatic replacement generally functioned better than the original Duofold parts, most collectors prefer their Duofolds to have original Duofold parts. 
Button fillers: This mechanism was Parker's answer to the lever, employing a spring bar which collapses and deflates the sac when a button at the end of the pen is depressed. If the push button refuses to function, it could be for one of two reasons. The sac might be petrified, or the spring bar could be damaged or missing. (Spring bars are simple to replace, so don't shy away from a Duofold if the filling mechanism is not working.)

WHAT TO AVOID PURCHASING
Just about any fountain pen is worth purchasing if the price is right. Even a fountain pen in the worst condition might yield one or two good parts. However, while prices are escalating, it is wise to avoid pens that have too many problems or are too difficult to repair. 

Piston-rod fillers: Sheaffer and Wahl-Eversharp manufactured pens during the 30s and 40s that employed a thin rod piston filling mechanism . Because this system did not require a rubber sac, it allowed the pen to have a larger ink capacity. The public must have been very pleased with this innovation because many of these pens were sold. Nevertheless, pens of this type are extremely difficult to repair. There are a few shops that repair these pens, but because they are more complicated and require special parts, the repair cost is usually higher.
