Ed, parts are getting harder to find and most that I'm seeing are at premium prices. Numrich has some parts but many are listed as out of stock. There are a few members here with great interest in hammer guns and may have what you need. I may be able to help you with the firing pin or a few other parts. Please send me a photo of the pin to 717-887-0545 or cedarclyffelodge@gmail.com. Quite often I have to get a machinist to make the parts
