It looks a lot like a CVA kit that I built in the late '80s/early '90s... Made by Armi San Marco. It came in the white(unblued) with machining marks that needed to be filed, sanded and polished. The brass frame was machined for the lock work but the outside was still a rough casting. The wood grips were quite a bit oversized and rough. I spent several evenings hand finishing it, and cold blued the barrel and cylinder. It shoots great. The bluing has turned a nice plum brown. I think I paid about a hundred bucks for it. .44 caliber takes .451, or .454 round ball but most can take .457 also. It's just a little harder on the rammer and you hand to load. CCI #11 caps are a bit loose on mine.
