Product Description
Type Vintage piston fountain pen, working perfectly.
Product Name Osmia Progress 732
Manufacturer and Year Osmia, Germany -- 1930s, guess based off of the clip and the celluloid pattern.
Length 4-3/4".
Filling System Uncommon pump filler similar to Parker Vacumatic. Turn the end knob to access the piston, and push and retract the piston to fill the pen..... you'll see the barrel fill, and it takes a few pumps. We have replaced the diaphragm with a Vacumatic diaphragm and it's working well. We will fully guarantee the filling system for a year from the date of purchase.
Color Black and gold-colored celluloid in a really cool diamond pattern. Gold plated trim.
Nib 14k Flexible Fine nib. It is labeled F near the piston knob. It has great tipping and writes smoothly with respectable line variation. We've read that the Osmia "Supra" nibs with a diamond imprint were considered "maxi-semi-flex" - we're not quite sure what they meant by that, but it's really nice! Please see the writing sample below.
Condition Excellent condition. The cap jewel is cracked and partially missing - it would likely have been diamond shaped and enclosed in a circle, but the shape is off and there's a ring of missing material. There is scratching on the barrel from capping. The color of the barrel has darkened somewhat to a medium brown. The barrel transparency is excellent. The section has some tool marks. The piston knob has scratching and some tiny marks. The cap band has brassing on the edges. The clip also has brassing on the sides and top shoulders, as well as around the edge of the tassie. Most of the nib masking has been polished away. The imprints are clear.
