The first pic of the single reciever is the one in question, yes it is a 98 Mauser but with a small receiver ring and still has the 1.1" barrel threads of a standard m98. The other two pictures are for comparison with a Belgian 98, they are the same except one is a small ring, the bolts even interchange. The small ring is marked Mauser mod 1928 and was originally barreled with a 17" carbine length barrel chambered in 7.65 argentine. The barrel is engraved, Armeria Alemana Buenos Aires
i picked this up as a complete rifle at a gun show and I intended to use it for a build project, I didn't even realize it was a small ring until I tore it apart.
At at first I was thinking it was a Mexican Mauser possibly built for Argentina but if I'm not mistaken the Mexican mausers had a smaller barrel thread.
Does anybody know what I have or have you ever seen one like it?
also do you think it would be safe to use for the project I have planned, .358 win ?
any help would be appreciated.
