Does anybody know if a Euroarms R&S cylinder is the same they used on their 1974 Beals NMA? I know I can file down the frame for a Pietta and that Uberti's will drop in for the most part but there's a bigger gap depending on the year "I read posts from several other Euroarms owners of different decades and there's measurements. So if anyone does have both or has had them please chime in and share your thoughts.
