Cotter pin c/w nut and washer

On the gearbox outer cover, that generally means a kickstart or gearchange lever pivot, where the pin, nut, and washer come as a set to hold the lever solid on its shaft. The catalog shows this part across a run of mid-to-late 1960s appearances, but we don't have enough here to pin it to one specific model or year — check it against what you're working on before you order.
The manufacturer code on file for this one says Lucas, but a cotter pin and nut isn't an electrical part, so take that tag with a grain of salt. This is simple gearbox hardware, not something out of the wiring loom.
