I cannot believe how long Numrich Gun parts have been in business, and how few people know about them. Try this:

I tried Ruger and Numrichs well as well as gunbroker, ebay, and some other places before posting. I should have clarified that. Ruger does not sell many No.1 parts. They said they have to be custom fit. I told them I am a gunsmith. They didn't care. I was posting in the hopes that someone knows of someone or somewhere that I might be able to get the parts I need. I really need a Breech block and two hammers. I can make the hammers easy enough but the breechblock is going to cost more in time than the repairs are worth.
