I guess I learn something every day. I thought the model 49D had 10 mm holes to attach the inner ring, and that the 10 mm bolts carried over to mods 57, 63 and 93. But evidently not. Can anyone confirm that early mod 49s had 7 mm bolts for the inner ring? I always wondered how, if at all, mod 57 and 63 rings were different from mod 93. It seems the mod 57 at least had smaller holes. What about mod 63?
