I was gifted this revolver by my father in law but can't seem to find details on exactly what it is. As for the markings I know it is an open top revolver cartridge conversion, .38 special imported by Traditions Firearms with a serial number of 629 (verified on both the barrel and the bottom by the trigger guard. Other than that, I have no idea what it is. I have contacted Traditions Firearms and they were no help at all. They couldn't tell me the model or anything. Only info I got from them was that their company hasn't produced open top cartridge conversion revolvers for many many years. I've been told it was an 1851 Navy replica and 1861 Navy and Army replica and an 1872 Army Conversion. I need to get parts for it and even Traditions Firearms said that it could either be a Pietta model or an Uberti model but they don't know which as they have done business with both companies. So not much help there. Any information would be greatly appreciated.
