Subject: [CR]Campagnolo track hub question

Are there different threads for the reverse-threaded ramp on Campagnolo track hubs? I ask because I have a Campagnolo rear track hub, with a 64 date, and the Campagnolo lockring fits smoothly on the ramp and screws in easily, though its threading is not indicated. An English threaded cog screws onto the cog threads. When using the Campagnolo lockring on another track hub, one marked as having English threads, the lockring fits loosely and does not secure a cog. Using a different Engish threaded lockring on the Campagnolo hub, it begins to screw onto the ramp, but then immediately tightens. It probably could be screwed onto the hub, but it would take force to get it on the ramp close to the cog.

I am asking then what threads, aside from English, did Campagnolo make track hubs, and would it have been common to have the cog threading one dimension and the ramp another?

Thank you.
