I have a 38 special pistol that belonged to my dad. It's a 6 shot revolver approx. 60 years old. It has Great Western Arms Co. stamped on the barrel, it also has "38 Special" stamped on the barrel, and a serial number on the bottom. It has no other markings. Does anyone know how I can find out what model it is? It needs a new firing pin, other than that, it would be functional. My dad had it nickel plated, however, shooting .357 magnums in it blew the plating off around the cylinder. I would like to have the plating removed and have the original finish restored. Any idea what the cost would be?
