The Conklin 75 Model is the largest size Conklin made in this model.
I have ultrasonically cleaned the NIB and feed. I 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 Toledo #7 NIB. I have cleaned, lightly buffed, and polished the barrel and cap to bring back the vibrancy of fountain pen and to protect the red hard rubber. This Conklin 75 measures 5 5/8" capped and 7 3/8" posted.
This Conklin is made of Black Chased Hard Rubber. The hard rubber displays a nice black color with no oxidation to speak of. The chasing on the barrel and cap are seen but is light. This fountain pen cap and barrel are in very fine 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 cap has the Gold Filled Conklin PAT May 28, 1918, Clip with the Smooth Gold Filled Cap Banding. The clip does display some wear which could easily be gold plated again. The smooth gold-filled cap banding is very clean with only a bit of wear on the lower portion of the lower lip of the cap banding. The barrel imprint is extremely difficult to see and is very light but the 75 model number can be seen. The crescent filler is stamped on both sides, "CONKLIN" on one side and "RED US PAT OFF CRESCENT" opposite side. 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 75 has a 14K Conklin Toledo #7 Nib. The actual iridium top on this #7 Nib has a medium point measuring roughly .87mm when measured with digital calipers. When writing a sample with this NIB, it writes with a medium to a double broad line. In the writing sample provided, the medium line measures at .72mm and will flex to a double broad stroke measuring at 1.23mm with medium to firm pressure when measuring with digital calipers. The nib is writing smoothly and is a pleasure to write with.
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 Crescent-Fill Fountain Pens that is extremely rare that individuals rarely get a chance to secure in their collection. For the collector, this is a "holy grail" vintage fountain pen to add to the collection. I would consider the pen to be in Very Fine condition - if the imprint was not worn I would grade it excellent. This Conklin is ready to write, if you choose to do so, or just add it to your writing arsenal collection.
