dolk, found this info for you on the net..... looks like EMF sold ASM revolvers then went over to PIETTA revolvers when ASM folded .............
If it says EMF it is an Armi San Marco revolver made in Italy.
Generally the quality was a little worse than Uberti. Earlier guns were pretty good, but later pieces, before ASM folded, had some bad quality control issues, which was why EMF and some other importers dropped them. By "earlier" I mean guns produced prior to approximately 2002.

EMF's Great Western II single action revolvers and Hartford model percussion pistols are manufactured by F.A.P F.LLI. Pietta. Established in 1960 by Knight Giuseppe Pietta, the company first entered the world of gunmaking by producing hunting guns, including side-by-side and over and under shotguns. In 1964, F.A.P. F.LLI. Pietta started manufacturing replicas of the firearms used in the American Civil War. Over the years, they have made an excellent reputation (in a very difficult market) for making quality black powder reproductions. In 2002, Mr. Davis, CEO/President of EMF Company turned to Knight Giuseppe Pietta to manufacture EMF's Great Western II line of single action revolvers. The joint efforts of these two great companies have resulted in the production of one of the finest single action revolvers on the market today!
