Acquired a vintage Pelikan 400 recently that some "silly person" (not me) decided to pull the nib outta (leaving just the feed), and that some other "silly person" (yeah, me) decided to try unscrewing ... and now all i really have is a spare feed in one hand and a pen with the nib-collar stuck down inside it in the other. (And a cap, over there on the floor somewhere.) So, the question is, naturally: Should i attempt to chisel the collar free and hope my other nib-unit will still fit (section's a little misshapen from that gold-mining-expedition trauma), or ... dig up a loose nib and try to jam everything back into the stuck collar? (Or should i just drill a hold thru the middle and hang it on the bathroom wall?...) (And then buy a different pen.) Advice appreciated, and thanks in advance.
