For your consideration, we are offering for sale this Rare Circa 1928 Conklin Senior Endura Rosewood Hard Rubber Fountain Pen. This fountain pen has been thoroughly taken apart, cleaned, and put back together and now is in wonderful writing condition.

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 sac. Hand polished the Conklin Gold Filled Clip, Smooth Cap Banding, and 14K Conklin Endura NIB. I have cleaned, buffed, and polished the barrel and cap to bring back the vibrancy and to protect the red hard rubber of this fountain pen.

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. The Rosewood hard rubber color on this pen is excellent and displays consistent color from the cap to the barrel. The Rosewood Hard Rubber Sr. Conklin Endura's are tough to get ahold of and are coveted by collectors. The cap has the Gold Filled Conklin PAT May 28, 1918, Clip with the Smooth Gold Filled Cap Banding. The clip displays some wear towards the top of the clip and along the right side. The cap banding displays only minor wear along the back edge of the banding - it displays light wear. The barrel imprint has worn away but would have read, "Trade CONKLIN Mark TOLEDO OHIO U.S.A. ENDURA". The lever filler is stamped with "PAT NOV. 17, 1925". This Conklin Endura is a Senior size that measures 5 3/8" capped and 6 7/8" posted.

This Conklin has a Lever Filler filling system. 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 has the Sr. Endura size 14K Conklin Nib. The actual iridium tip on this Endura Nib has a fine point measuring roughly .55mm when measured with digital calipers. When writing a sample with this NIB, it writes with a fine to a medium stroke/line. In the writing sample provided in this listing, the fine line measures at .58mm on the horizontal strokes and measures a medium .88mm line on the downward strokes with medium pressure when I measured with digital calipers. This Nib is very rigid but writes smoothly. TThe 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 iconic Conklin Senior Endura Fountain Pens you don't always get a chance to secure in your collection. Conklin Rosewood Hard Rubber displays brilliant and vibrantly. If the imprint on the barrel was easily seen I would grade in Excellent but without I would consider this pen in Fine to Very Fine condition. This Senior Conklin is ready to write, if you choose to do so, or just add it to your writing arsenal collection.
