I bought a neat, early 1900s German built DR with the top rib set up with claw bases but missing the rings. The rear claw is fairly standard, and the scope/rings from my 1926 Funk fit that just fine. However, the openings in the front claw mount is a bit wider and a tad longer than the 'standard' mount on the Funk which is the same configuration as that on a Sauer I own from approximately the same vintage.

Does anyone know a source of claw mount rings? I have a recolection of someone in the Nevada area, but right now I am drawing a blank. Any help would be appreciated. Dave
