I found a site back a while ago, I can't remember for the life of me what it was called, but it had all the mauser codes and how to decipher them. Try some searchs, thats how I found it. It helped me track down info on the several I have, I'll look later and see if I can find it again. It was an really helpfull site. It looks like a mitchells to me too, is it import stamped, most of the ones I have are not other than a few recent purchases from the last 3-4 years, I think I got about a half dozen Mausers, or more I've allways liked them very much.
