Did Regina have any consistent marking system for the early freewheels to indicate BSC vs. Italian threading of the body? I seem to recall having some that were marked F.I. on the rear mounting surface for "Inglese" threads at one point, but was that convention always used? If I have some that are unmarked, are they definitely Italian threads? I have some that have a circular groove cut into the rear face of the body - does this signify anything about threading?
