Norton Extension
A Norton chainguard extension flap, per our 1975 catalog listing.
This is a Norton part listed simply as an extension in our records, and the catalog title we have on file calls it a chainguard extension flap. It shows up in the parts-book figures covering the swinging arm, suspension units, and chainguard area, which points to it being a piece that extends the coverage of the rear chainguard.

Our record for this one is thin. We've only got a single catalog appearance, tied to the 1975 model year, and no further detail on material, size, or how it mounts. If you're trying to match this against what's on your bike, the safest bet is to compare it physically or give us a call before you order.
Since this comes out of Norton catalog data rather than Triumph, keep in mind it's a Norton-specific piece, not something you'd cross over onto a Triumph chainguard setup.
Sorry if we got something wrong here. If you think this information isn't correct, .
