Norton Mainshaft
A Norton Commando gearbox mainshaft, part number 06-0384.
This is the mainshaft out of the gearbox, part number 06-0384. The catalog title backs this up as a Commando part, so this is a Norton piece, not a Triumph one, and it belongs with the gearbox internals shown in the shell, gear cluster, and sprocket layout.

The mainshaft is the shaft the gear cluster rides on inside the gearbox shell, carrying drive through from the clutch side through to the output sprocket. Beyond that, our catalog record on this one is thin - a single appearance tied to 1975.
