Malcolm!
I have an even stranger M-S scope problem. A M1910 apparently rebarrelled to .22 Varminter way way back when. The mounts are clamps, screw holes threaded metric, and I need a scope a little smaller than 7/8s. Good luck finding your parts. I'll bet one of our MCA member in Germany might be able to come up with something.

Texas is already getting hot and humid. Thank God for a/c!
