GEAR,C/B B31/B33
A gear listed for BSA B31/B33 models, filed under Triumph part number 42-0120 with limited catalog detail on file.
This is a listing carried under Triumph part number 42-0120, but the catalog description itself points to B31/B33 - which are BSA models, not Triumph. We don't have much more on file for this one beyond that basic description, so we're not going to guess at what subsystem it lives in or how it mounts.

Given the description names a BSA model designation, this gear likely belongs in a BSA parts catalog rather than a Triumph one, even though it's filed here under a Triumph-style part number. If you're trying to match this up to a BSA B31 or B33, give us a call and we can go over the details with you before you order.
We'd rather be straight with you: the record here is thin, and we don't want to invent specifics about fitment or function that we can't back up.
