In 1939 Waterman began manufacturing the 100 Year fountain pen to the public. The first year fountain pen came with the Cap Clip that went over the top of the cap, which this one is not - this is the 2nd Year Waterman Hundred Fountain Pen but is the 1st year they made an Oversize which this fountain pen is. Also, the first year - 100 Year Waterman Fountain Pens were made from Lucite but were changed back to celluloid after 1940.
I have ultrasonically cleaned the NIB, feed, and section. Hand cleaned the inside of the barrel and cap. Cleaned and polished the outside of the cap and barrel. Replaced the old rubber sac with a new rubber sac. Hand polished the Gold Filled Barrel Banding, Gold Filled Clip, Gold Filled Ideal Lever Box Assembly along with the Waterman 100 Year Semi-Flex NIB.
This fountain pen is made from lucite in transparent Green Lucite. The coloring is an amazing green color with no damage to either the cap or barrel. The back of the cap has the imprint at the center of the barrel that reads, "WATERMAN'S REG. U.S. IDEAL GLOBE LOGO PAT. OFFICE MADE IN U.S.A. HUNDRED YEAR PEN". The barrel has the gold filled banding that is clean and secure to the ribbed barrel. There is no wear or brassing to any of the gold filled trim on this fountain pen.
This Waterman has been preserved handsomely and a wonderful example. The threads on the cap and barrel are excellent with the cap always securing tightly to the barrel. There are no monograms on the cap or barrel. There is no crazing, cracks, nicks, or damage to either the cap or barrel. This Waterman Hundred Year is an Oversize size fountain pen that measures 5 3/8" in length capped and 6 3/8" posted.
The lever and box assembly have been cleaned and oiled. It works flawlessly and smoothly. The lever is crisp and clean with no brassing. I have tested the filling mechanism with water and fills wonderfully.
Here is the "fun" part of this fountain pen. The NIB is the 14K Waterman Hundred Year that is semi-flexible and writes so smoothly. When measuring the actual tip of the NIB, it measures at .67mm with digital calipers. When writing the sample in the listing images, the NIB writes with an extra fine line measuring roughly .43mm with very light pressure and flexes up to a broad stroke of 1.12mm with normal pressure; I didn't want to overextend the NIB's capabilities. The writing sample provided was done with the actual pen in the images that are listed for sale. The writing sample was used by dipping the NIB in Parker Quink Blue Ink.
Any specks of white in the images are from the cotton that I used to clean the barrel and cap.
Finding a Waterman Oversize Hundred Year Pen is elusive and finding one in this condition is extremely difficult. This is a Holy Grail Waterman Hundred Year Pen that I would consider the condition to be in Excellent+ condition in the desirable Green Transparent Lucite coloring. Certainly, this is a collector grade writing instrument.
