Product Description
Type Full size fountain pen with a nicely flexible nib
Product Name This pen is imprinted "Cosmos" on the cap. We've had a similarly imprinted BCHR pen that was an eye dropper filler.
Manufacturer and Year Unknown, probably teens or 1920s. (The chasing pattern is the one called Scallop #3 and was used by Gem, MacKinnon, Parker, Sheaffer, and Waterman. See this incredibly helpful page on chasing on Richard Binder's site.)
Length 5-3/16"
Filling System Matchstick filler. You operate the system by rotating the ring on the barrel and exposing the small round hole, then depressing the pressure bar via a matchstick while holding the pen tip in ink. We cleaned and re-sacked and tested the pen and it works very well.
Color Black chased hard rubber with no clip. We're not sure, but this pen may have had the hard rubber treated with a coat of black, as the color is very uniform and slightly pebbled.
Nib Flexible Warranted #2 14k nib. See writing sample below.
Condition Excellent condition with no cracks. This is a unique, dark black pen, with intact chasing. The smooth black upper part of the barrel has some marks caused by the cap lip. The mid-barrel has some small dot marks. The end of the barrel, under the filling ring, has a few bite marks. The cap looks quite nice with just some small marks and scratches near the top and along the flat top edge. The "Cosmos" imprint is clear.
