>>>Can someone please offer any info on a few drilled rings I came
across.
These are nicely finished silver anodized rings, factory drilled (a la
Eddy) and are simply inscribed with "S-54" (or whatever the number of
teeth). No overshift pins and no other manufacturers ID. Perhaps
Sugino?... Possibly late 70s?... 80s?
