I am looking for someone to work on 1891 Argentine Mauser bolt. The firing pin broke on my Mauser and this caused the ****ing piece to fall out. I have a new firing pin, ****ing piece and safety. I need help putting them back together. According to several places on the web, you have to bevel the ****ing piece to make it work. Not sure why new parts wouldn't work, but that's what they told me. Does anyone here work on old Mausers or know of anyone who does.
