Sorry for the drift OP, but I have to ask Mannlicher about his 45. A plated 25?, a 625 with pinned barrel? A 5" barrel? WTH? Spare cyl. from a later model as I see the longer cyl. latch slots, & that's about all I recognize.

Was going to tell OP about my my mountain gun that has been cut for ACP moon clips & still can shoot 45 Colt, but this is another approach.
