Dave bought the G Special from me. I did many miles on it (including a couple of Irish rallies) mwhen it had the foot change conversion and found it a lot easier than the hand change. I remember that someone, I think it was Con Money, converted a 4 speed hand change on a Cammy by using the stop mechanism from a CP box. As you can see it is very similar. I have often wondered if it could be used on 3 speed box.
