BSA Lockwasher, heat sink and steady stay (5/16")
A 5/16 inch lockwasher used at several points including the heat sink and steady stay, per the catalog listing.
This is a 5/16 inch lockwasher, the kind used under a nut to keep it from working loose over time. The parts book lists it under lockwashers for a heat sink and steady stay, and it turns up across a wide range of figures in the catalog — frame, gearchange mechanism, swinging arm and rear brake control, footrests, oil tank and toolbox, steering head, front and rear mudguards, front forks, crankcase, and more.

Given how many different assemblies call for this same washer, it looks like a general-purpose fastener used in several spots rather than something tied to one single job. The catalog doesn't spell out exactly which of those listed locations applies to your bike, so if you're chasing down a specific washer, it helps to know which assembly you're working on before you order.
Older parts books may also list this under the alternate form 36-382. Same physical part, just a different way of writing the number.
