I seem to remember seeing something about that in an early sixties Hot Rod magazine. Do the have an online archive someplace? I think one of the benefits was being able to change the cam timing without completely disassembling the front of the engine.
Do you have the crank gear, verniered cam hub and cam gears that complete the system? They will be essential to using what you have, but I don’t see them in the photos.
I do not but hopefully off I can find info on this and then start to build it back, that's what I did with my potvin and chain drive.
