I finished this up today. It is a fountain pen made from vintage cellulose acetate and argentium silver. I fabricated all trim from wire and sheet stock. The pen is about 5” long capped, so it’s nice and compact for carrying around. I began this pen months back, and somehow it got lost along the wayside. I just found it again and decided to to make some trim so I could finish it up. It uses a Bock #6 nib, and while the pen is a short over all length, it can fit a full size converter in it. I don’t remember all the thread sizes because I’ve since changed them, but this was one of the last pens I used single start threads on.
