What Buchseman said.

In addition, in the distant past I have bench-made several sets of rings to fit existing claw bases. It's not difficult but certain techniques are required. Tommy Bish shows how to do it in one of his books but I found his method to be slightly flawed for my purposes. In any case this method usually involves using modern split rings rather than the original configuration. Lots cheaper for existing bases but not nearly as authentic.
