Oh boy! Great Great guns! I never owned a Smith with King modifications but back in the early 70's I did own a Colt single action, 5 1/2", .44 special, nickel, 1 piece ivory grips that was special order 1n 1936 for a colonel of ordnance and sent from Colt to King and fitted with a reflector front sight, King rear sight, "Cockeyed" hammer, and wide target trigger, and a short action conversion. The revolver was 99% condition with a carved Heisser holster. The gun lettered from Colt. Unfortunately, I made my living as a "picker" of antique and collectible guns and my family had to eat so I couldn't keep it- nor could I keep the couple of Registered 357's or the first month of production 5 screw pre-29 or the auto rifle. I'm still over weight so I must have eaten well....
