I went to an antique store this past weekend and found this pen on sale. I was intrigued by its size (it's almost exactly as long as a Kaweco Al-sport when capped), the 14K gold nib, and a body in near-perfect condition.
The pen was being sold for $15 because the tines were sprung; one of the tines was overlapping the other. I managed to bring the price down to $12, and left the store with a project.
After a few minutes of adjustments, I was able to unspring the tines and write with the pen. The flex is strong with this one! Being my first full flex pen, I was impressed by the line variation I could squeeze out. The ink keeps up for the most part.
After getting the pen to write, I wanted to know what kind of pen it was. It looks like an early 1900s pen with full-flex. The nib says "Warranted 14KT.", and it looks like a real gold flex nib.
The feed also looks real, because its a very simple ebonite feed with a few channels carved into it; no fins, nothing fancy.
What threw me off was the distinct lack of filling mechanism (i filled it by removing the nib and feed and dropping the ink into the barrel), any written logo or name on the barrel or cap, any clip, or any other metal components. The plastic body also feels modern. I'm not sure if I would be able to tell the difference between a modern counterfeit and an antique pen, though.
Does anyone have any information about this pen?
