I have a 4.5" 41AE barrel. Marked 41AE, but doesn't have a serial like my Jericho barrels. It fits my Jericho, and presumably a Witness and I guess some other pistols. It still has cosmoline on it and looks like it has never chambered a round.
I also have 50 new IMI headstamp 41AE cases, $35
and 100 Hornady 210 gr XTP bullets. $35
All prices include shipping, so I'll cut a little off if one person takes everything.
