O1 is very stable. A2 is even more so.

I use O1 for pen bushings because they maintain concentricity and size after heat treating. Heat treating is done with used motor oil (non-synthetic) and a propane torch. Never had a bad part yet.
Full of ideas, but slow to produce parts

Your co-worker inherited a rare bird. Not too many "triple" actions around. Single shot, bolt action and semi-auto all rolled into one package. Nice.

Willie,
Do you have any idea what it's worth? We haven't had any luck on trying to find its value. To him it's priceless since it was his grandfather"s. He just wants to get it back to the point where he can use it. He'll never sell it.

I took a look at it and it looks like it would be a fun. challenging project to try and make. No lose if I don't succeed. My question is what type of steel would be appropriate? I was thinking pre-hard 4142 steel. Any advise would be appreciated. I'll try to get some pictures of the part and post them tomorrow but I believe it's the breech.
Attached is a crappy picture of the rifle that I found with the help of Mr. Google.

Good to have a value for insurance reasons.
That looks to be a complex part Ed, I'm sure you will enjoy the challenge. I'll be watching your progress with interest. Personally, I'd go with O1, as Tom has suggested.
