For your consideration, we are offering for sale this Extremely Rare and Uncommon Restored Circa 1911 Waterman #415 Sleeve Filler Black Hard Rubber with Sterling Silver Trefoil Overlay Eyedropper Fountain Pen. This fountain pen has been thoroughly taken apart, cleaned and put back together and now is in wonderful writing condition. Such an exceptional fountain pen - Large Sterling Overlay Waterman are uncommon to acquire and a Sleeve Filler in Sterling is extremely difficult to find.

Ultrasonically cleaned the NIB, feed, and section. Hand cleaned the inside of the barrel and cap with mineral oil. Cleaned, buffed, and polished the outside of the cap and barrel. Hand polished the Sterling Silver Cap, Sterling Barrel and Waterman 14K #5 NIB.

This fountain pen is made from black hard rubber with Sterling Silver Overlay in what is known as the Art Nouveau or Trefoil pattern. This pattern was in production from 1907 to circa 1923. The Sterling Silver overlay is gorgeous displaying a beautiful Art Nouveau look. All Sterling Silver overlay has been polished to shine brightly. The Sleeve portion of the barrel is stamped, "WATERMAN'S IDEAL FOUNTAIN PEN STERLING". The butt end of the fountain pen has imprint model number "415 S.F." The cap is a slip type cap with the cap always securing tightly to the barrel. There are no monograms or personalizations to either the cap or barrel. There are no cracks or repairs to the hard rubber or Sterling Silver overlay. This Waterman #415 Sleeve Filler measures 5 3/4" in length capped and 7 1/8" posted.

This Waterman Fountain Pen is a Sleeve Fill type - the barrel sleeve slides towards the end of the barrel to reveal the pressure bar that one pushes down/release to take in the ink. Slide the Sleeve forward to close the pressure bar. The filling system has been restored and is in proper working condition.

This Waterman has a wonderfully smooth #5 WATERMAN IDEAL NEW YORK Semi-Flex Nib. The iridium tipping is in excellent condition with the point measuring .78mm when measured with digital calipers - a medium nib point. When writing the sample in the listing images, the NIB writes with a fine to double broad line. The fine line measuring roughly .53mm with light pressure and flexes to a double broad stroke of 1.52mm with medium to firm pressure when measured with digital calipers. This Ideal Nib writes smoothly with a soft flexible nib - it is a pleasure to write with. The writing sample provided 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.

These large Waterman Fountain Pens overlays are extremely difficult to find especially in Sterling. To give some context, this 415 Sleeve Filler is longer and has a larger diameter than a Parker Senior Maxima. This #415 Sleeve Filler Sterling Art Nouveau/Trefoil Pattern Overlay Fountain Pen is a difficult example to find and considered very rare. I would consider the condition of this fountain pen to grade in Very Fine to Excellent condition. Such a significant Waterman example that one can add to their writing instrument arsenal that very few people in the World will have.
