I picked up a 350 at the thrift store today, and am trying to get an approximate age on it just so I can know a little more about it. I've got a dark-ish picture of the cap/clip and the section/nib posted here:
It's hard to tell from the photo, but this is a Carmine stripe color. It's also vac-fil, which seems to be problematic for the amateur pen goof like myself. Unless I've missed the signs, this seems to be a standard "Balance" model.
Many thanks for any help you can provide.
(edits as I've found out more)
