I know the classifieds would be appropriate, but the only people interested would be on the is board.
I actually have an Uberti 1860 follower that has been modified to take short rounds with the side set screw. I used it Civil War reenacting to feed heavily crimped 38-40 made into blanks in either a 45 or 44-40 Henry. It would work on .44 Russian of .45 Cowboy. I'll do $60 shipped, since a new lifter is $60 plus shipping from VTI.
