I seem to remember commenting on a thread somewhere about flatting down the alloy casting on the underside of a conventional 3 speed ball change top to improve the ball joint fit by taking up slack.
I was cleaning up a "reverse pattern" top today and noticed that it seemed to be different, as there was a steel cup under where the ball would sit, above the screw-in alloy retainer. I'm now not sure whether the conventional pattern top was original, or missing a part, or... whether I'm getting confused with the earlier gate design.
Could anyone clarify whether the altered ball change top was improved in design for wear to surfaces as well as the swapping of gear positions? Or have they always had the steel cup below?
