SEALING WASHER BSA FORK
A rubber sealing washer for the BSA front fork top, also cataloged under Triumph numbering.
This is a sealing washer for the front fork on BSA models, and it turns up under the Triumph part-numbering system too since the two makes shared this piece for a stretch. The catalog description calls it out plainly as a BSA fork item, so if you're working on a Triumph unit single from the same era, it's worth checking your own parts book to confirm this is the washer called for.

It's a simple rubber washer that seats at the top of the fork to keep oil where it belongs and keep water and grit out. Not much to say beyond that - it's a wear item, and if the old one's gone flat, cracked, or hard, it's not sealing anymore.
We don't have much more detail on file for this one beyond what's above. It also shows up under the alias G129 if that's the number printed in your book.
