BSA Stiffener plate
A stiffener plate from the rear mudguard and chainguard assembly, likely a BSA part rather than Triumph.
This is a stiffener plate that lives with the rear mudguard and chainguard assembly. Its job is to add rigidity where the guard mounts up, keeping that section from flexing or cracking loose over time.

The catalog places it under the rear mudguard and chainguard figure, with appearances logged for 1969-1970. Given the manufacturer code and the grounding info pointing at A50/A65 fender bridge hardware, this looks like a BSA part rather than a Triumph one, so don't order it expecting it to bolt to a Triumph guard without checking first.
We don't have much more detail on this one beyond the figure placement. Call the shop and we'll confirm fitment before you order.
