All I can say is I know a collector in Ohio that had all the tooling made to manufacture bases and dovetail mounts. He had a couple cast mounts in incomplete machining state and sold them along with the custom made tooling. I don't trust these as far as I can spit.
AFAIK mostly around the 3xx N-range.
