Answer
Hello Jason. I must ask you to re-enter all the wording on the firearm. I have found no information on M. 31 F.B. Radom 1932 caliber .22. Are you sure it is a Mauser? Are you sure of the spelling of Radom? I really want to help you find parts for it, but I could do it better if you can send a photo.Charles Gage
