I was recently given an H&R "the American" .32 caliber double action revolver by my step father. I was wondering if anyone could tell me what kind of .32 ammo this pistol uses and if it is still available. Also the nickel finish is pretty well worn and i was wondering if it is possible to have it refinished nickel or even blued to restore it? All parts are there and the lockup and action seem to be in good working condition. Any help you could offer would be greatly appreciated.
