I have been given a 1938 commercial mauser, 7X57 with double trigger, round to octagon barrel in excellent condition, both barrel and wood are in excellent condition. The question, I have the claw base mounts and claw scope rings, the rear scope ring is 1 inch in diameter and the front scope ring is 1 5/8 inch, does anyone know where and what type of scope will fit these rings. I have been looking all over the internet.
