Smith & Wesson model 36-1 .38 caliber, five shot. I purchased this pistol NEW in 1978. It was manuafactured in late 1976-early 1977. Rare model with 3 inch barrel. Has been well maintained, cleaned/oiled following every use, no corrosion or rust. Went for long periods of time between use. Have used quality (clean) range ammo.
