A George Lawrence Model 79 belt is their Gunslinger II model. the Model 79 holster is leather lined to allow free cylinder rotation when cocking (!) and was popular back in the fast draw fad. I could not find a listing for a 732, but a 532 fits a 4" N frame. Do you have a 6.5" N frame to try the fit ? Otherwise I would guess some single action revolver.
