Sturmey Archer Competition TT lightweight vintage motorcycle gearbox

This small Sturmey Archer TT gearbox is a bit of a mystery. I have plenty of information on the TS model. As I’m not a specialist in Sturmey Archer motorcycle gearboxes, I don’t have detailed records of any boxes that they supplied for competition. All that I know is that the “TT” stamp suggests that it was a competition box.

The only reference that I can find to a TT box, is an advert for a shell only for a 3-speed version that was model type 10P. It was also a 2-stud box.

It’s 2-stud. So, it’s for early machines up to about mid 1920’s. The sequential number is 559. If it helps, there is a tiny stamp on the case, just behind the pulley that says “0.13”.

Condition: I’ve not used it. I can confirm that it turns by hand and doesn’t make any horrible noises when I turn it.

The casing is intact. It doesn’t have cracks but it does have a ding in the side of casing. It is supplied with the belt pulley as shown. It’s dirty, but decent. The pulley will need a little bending into shape with some heat.
