I have a reproduction Colt 1860 Army that has a brass frame and a 7.75" barrel. The receiver is engraved and it has a shorter grip than most 1860's. I'm trying to figure out who made this. It is marked made in Italy and has 3 screws in the receiver. The other side of the barrel is marked, Model 1860 Army .44 Cal. There is an AH and PN on the receiver.
