Here, i think yours would be the Modified MKII Gearbox, came out a little later with the collar behind the clutch lever return spring, and a new overrun clutch type in the wheels.

If this does not match yours i will put up the other one, i am currently scanning what i have in the library and sending it to Bruce for the manuals section, i will make sure to get my section on the drive systems that this is from across soon.

Cheers
Ty
