BSA Spring washer, damper bottom mounting (3/8" × 3/4" × .056")
A 3/8" x 3/4" x .056" spring washer for the rear damper's bottom mounting bolt, shown in several 1969 frame and chassis figures.
This is a spring washer used at the bottom mounting of the rear damper (shock absorber), sized 3/8" x 3/4" x .056". It's a small piece but it does a real job — spring washers keep the mounting bolt under tension so it doesn't work loose from the vibration a running twin puts through the frame.

The part shows up across a handful of figures in the 1969 catalog year, including frame, footrest, swinging arm, and rear brake control drawings, which tells you this is a general-purpose fastener washer used at more than one point rather than something unique to a single bracket. If you're chasing one down for a rear damper lower mount, this is the washer the parts book calls for.
