I don't know the model, the groom who is giving it to me is on his honeymoon, so I can't see it again for a week. I'll update the OP when I find out. As to the bent bolt discussion, I've found several bent bolt kits I like. I'm going to do that and open up the optics options. As was stated. If I'm worried about historical significance, I can buy another one.
Edit: Based off of pictures, I think 91/30.
