I just picked up a Carter's black hard rubber fountain pen at a local auction. It's moderately oxidized, and has a fair amount of wear, with significant brassing of the (single) barrel ring, clip, and lever. The sac, of course, is nothing more than crunchy bits. Nib seems to be a generous semi-flex, and lacks the "INX" stamp of (earlier? later?) pens.
I understand that Carter's was in the pen manufacturing business for only six years, 1928 to 1932-ish; I'm guessing that would make them fairly rare? Most of the online examples I've seen are fairly attractive pens, in a number of colors/patterns; this is a plain-Jane, just smooth, black rubber, with a red stripe just below the end of the cap.
I have run across all kinds of references to numbers on the end of the barrel, yet this one seems to have no numbers at all; not the slightest hint of numbers; either they were deliberately removed, or it never had any, so I can't accurately identify the pen model. Can this fact be used to date this pen?
And on a more practical note: how difficult are these pens to break down? I'd like to re-sac it, and do a thorough cleaning of the feed, but this is possibly the tightest-fitting section and nib/feed I've yet encountered. I believe the section is a friction-fit; can anybody correct me here?
Any information or pointers on this pen would be appreciated
