Ahoy ! I can't search the Archive to save my soul. Can someone please point me toward the description of the markings on TA bot brkt cups that indicate Brit, French, Ital etc. thread? I recall the presence and quantity of rings on the cup indicated the thread. Aussi: 1/4 inch ball bearing? Thank you. Richard Cielec Chicago, Illinois; U.S.A.
