I have ultrasonically cleaned the NIB and feed. I have hand cleaned the outside and inside of the cap and barrel with mineral oil. Replaced the old rubber sac with a new, Silicone sac. Hand polished the Conklin Gold Filled Clip, Smooth Cap Banding, and 14K Conklin Endura NIB. Lighty Buffed, Polished and Waxed the barrel and cap to bring back the vibrancy of fountain pen and to protect the red hard rubber. This Conklin Endura is a Senior size that measures 5 3/8" capped and 6 7/8" posted.
This fountain pen cap and barrel are in great condition with no chips, cracks or repairs and the cap always securing tightly to the barrel. There are some very light scratches and just point it out for clarity sake - I personally wouldn't take a chance trying to remove the scratches and possibly compromise this extremely scarce pen. The red hard rubber color on this pen is excellent and extremely scarce. The cap has the Gold Filled Conklin PAT May 28, 1918, Clip with the Smooth Gold Filled Cap Banding. The clip displays no brassing. The cap banding has two minor spots on the edge that display only very minor brassing. The barrel is clearly stamped with, "Trade CONKLIN Mark TOLEDO OHIO U.S.A. ENDURA". The lever filler is stamped with "PAT NOV. 17, 1925". I have tested the Crescent filling mechanism with water and fills as it should. The Crescent Filling System works great and operates as it was intended to.
This Conklin Endura has a 14K Conklin Endura Nib. The actual iridium tip on this Endura Nib has a fine/medium point measuring roughly .59mm when measured with digital calipers. When writing a sample with this NIB, it writes with an extra fine to a broad stroke line. In the writing sample provided, the fine line measures at .58mm and will flex to a broad stroke measuring at 1.12mm with medium to firm pressure when measuring with digital calipers. The writing sample was done with the actual pen in the images that are listed for sale. The writing sample also used Parker Quink Blue Ink by dipping the NIB ink.
Any specks of white in the images are from the cotton that I used to clean the barrel and cap.
This is one of those vintage Conklin Senior Endura Fountain Pens you don't always get a chance to secure in your collection. For the collector, this is one of the "holy grail" vintage fountain pens to secure for the collection. Conklin Red Hard Rubber is very scarce and should be a deserving collection. It is Conklin is ready to write, if you choose to do so, or just add it to your writing arsenal collection.
