In 1948 Sheaffer stopped using celluloid. It makes me a little sad. However, the injection molded plastics they turned to did have some interesting colors. I like the Sheaffer umber pens. It's a deep and rich color that I find pleasing. Pens in this color seem to be less common than the typical black.
Another uncommon feature of this pen is the standard, open nib. In 1942 Sheaffer introduced the Triumph pen. They called the nib the Sheath-Point but today collectors universally call them Triumph nibs. The overwhelming majority of Sheaffer pens made from 1942-1948 (the last Triumph model) carried a Sheath-Point nib. Though there were a few models with more traditional nibs.
This pen has been well kept. The plastic is in very nice condition and the ink view grip section retains much of the original green hue. The ink windows tend to darken with exposure to UV or staining inks. The feed has a few damaged fins but this does not impact ink flow or performance. The manufacturer's imprint includes a price code 875 for $8.75.
The extra-fine nib has been adjusted to write a wet, smooth line. The Vacuum-Fil system is guaranteed for at least one year provided Noodler's ink is strictly avoided. That stuff stains plastics and melts rubber filler components.
