I have ultrasonically cleaned the NIB and feed. I have hand cleaned the outside and inside of the cap and barrel. Replaced the old rubber sac with a new, rubber 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 celluloid. This Conklin Endura is a Senior size that measures 5 1/4" capped and 6 5/8" posted.
This fountain pen cap and barrel are in good condition with no chips, cracks or repairs with the cap always securing tightly to the barrel. The black and pearl celluloid color on this pen is darker on the barrel than in the cap. The cap has the Gold Filled Conklin PAT May 28, 1918, Clip with the Double Ring Gold Filled Cap Banding. The clip displays some brassing at the top portion of the clip near the "Conklin" stamping. The cap banding displays only very minor brassing. Overall the gold filled trim display rarely quite well and bright. The barrel is 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 filling mechanism with water and fills as it should. The Filling System works great and operates as it was intended to.
This Conklin Endura has a Huge 14K Conklin Endura Stub Nib. The actual iridium tip on this Endura Nib has a medium point measuring roughly .83mm when measured with digital calipers. When writing a sample with this NIB, it writes with a fine to a broad stroke line. In the writing sample provided, the fine line measures at .46mm on the horizontal line and will flex to a broad stroke measuring at 1.23mm with medium to firm pressure when I measured with digital calipers. This Nib writes incredibly smooth, I cannot emphasize this enough. The writing sample was done with the actual pen in the images that are listed for sale. The writing sample was performed 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.
This Conklin Senior Endura Fountain Pen is an elusive Senior sized pen that would be a great user-grade specimen to add to your collection. I would grade the pen in fine condition - it isn't perfect but better than many others. It is ready to write with or just add it to your writing arsenal collection.
