Replica Arms of Marietta, Ohio was bought out by Navy Arms of New Jersey who continued to mark their products with a circled "RA" logo for some time afterwards. Replica Arms imported the large frame (Walker/Dragoons) and small frame (Baby Dragoon/Pocket/Wells Fargo) replicas from Armi San Marco but started importing their medium frames (1851/1860) from Uberti at some point. Navy Arms continued this dichotomy until Uberti started making the large and small frame replicas and they then bought exclusively from them. ASM logos are found on the left side of the frame, the underside of the frame in front of the trigger guard or on the barrel either on the side or hidden by the loading lever. Their logos include: SM, ASM, Marco, San Marco, Armi San Marco and a pyramid with the letters "ASM" interlocking and overlapping. CVA Walkers (and other models) of that time period were also made by ASM so their wedges should also work. I would set up a search on Ebay and run it every day or so for Sporting Goods/Hunting/Wedge and see what comes along. Good Luck!
