Logic dictates there must have been French threaded fixed cogs that were
probably the same thread as a French freewheel. If you still have one of
those gears, you may want to try it on a known French threaded hub.
It follows there may have been a different "French" threaded lock ring.
Ah, those French, "vive la difference!"
