Is it possible that only the reciever was made by ASM and the gun finished by another maker? Steffano Fausti and Sons (which still exists)? ASM made some very nice replica guns later on; their "Spaghetti Colt" clones are real clones--parts interchange with a First Generation SAA perfectly.
San Marco also has a martial implication; the Venetians being a very warlike naval power at one time--they rented their navy to anyone with the coin and their ships' "infantry" were legendary. The present Italian "naval infantry" are known as "San Marco Marines."
