For your consideration, we are offering for sale this Extremely Rare Circa 1915 Sheaffer #3 Mottled Red & Black Hard Rubber Self-Filling Fountain Pen. This fountain pen has been serviced with a new sac and is now in wonderful writing condition.

I have replaced the old rubber sac with a new sac. Hand polished 14K Gold #3 Self-Filling NIB. I also cleaned, polished, and waxed the barrel and cap to bring back the vibrancy and to protect the hard rubber of the fountain pen. The red & black hard rubber color of this pen is lovely but displays minor oxidation.

This fountain pen cap, section, feed, and barrel are in magnificent condition with no chips, cracks, teeth marks or repairs with the cap always securing tightly to the barrel. The Nickel Plated Lever is in excellent condition and operates as it should. The barrel has a very light imprint that reads, "PATD. AUG. 25, 08. DEC. 19, 12 PATENTS PENDING SHEAFFER'S SELF FILLING FOUNTAIN PEN FORT MADISON, IOWA USA". The top of the cap (yes cap) is stamped with "3" also is an imprint that reads, "TURN with a pointing finger". There are no monograms or personalizations on the cap or barrel. This Sheaffer Mottled Self-Filling Fountain Pen is a #3 size and measures 4 3/8" in length capped and 5 5/8" posted.

I have tested the lever filling mechanism with water and fills as it should.

This Sheaffer has a #3 Self-Filling 14K Nib. The actual writing portion, the iridium, of the 14K Sheaffer NIB has a fine point measuring roughly .56mm when measured with digital calipers. When creating a writing sample, the NIB writes with a medium to triple broad stroke/line that varies between .69mm to 1.80mm when measured with digital calipers. The writing sample 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.

This is a very Rare Sheaffer Fountain Pen in Mottled Hard Rubber. This Sheaffer would grade in Very Fine Condition. The coloring of the barrel and cap is very good with light oxidation. Having an example of a Mottled Sheaffer from this era with no damage or cracking is significant as these do not come up for sale very often. A very significant fountain pen to add to your writing arsenal collection.
