BSA 'D' washer, silencer clip
A 'D'-shaped washer used with the silencer clip hardware on the exhaust mounting.
This is a small 'D'-shaped washer used with the silencer clip mounting on the exhaust system. The catalog places it in the OIL TANK, TOOLBOX, SILENCERS section, so it's part of the hardware that helps secure the silencer mounting point at the back of the bike rather than anything inside the engine.

Our records show this one appearing in catalog entries from 1969 to 1970. It's a simple washer, not a wear item, but it's easy to lose track of when a silencer clip gets pulled apart for service, so it's worth keeping a spare on hand.
