early CVA locks and some others had a flint hammer with an off set that was supposed to hit the top of the lock as a stop to keep it from bashing the pan. I believe the early Italian guns were similar. The Italian locks do come up on the online auctions, but they are far and few between compared to the CVA and traditions parts. Sometimes those guns were just copied from another maker. As it making molds from the competitions parts and make exact copies. I understand that Pedersoli purchased machinery and molds from other companies when they phased out of the black powder business. A pedersoli may fit. I would check in person against one before paying out for one. Take the hammer pieces and compare it side by side to a CVA or traditions. Deer Creek in Indiana sells CVA parts reasonably.
