CRANK NUT BSA B44/50 LATE
Crankshaft nut for the later BSA B44/B50 engines.
This is a crankshaft nut for the BSA B44/B50 family, listed in our records as the later-type part. It's a BSA part, not a Triumph one, despite showing up in a Triumph-focused catalog run — the description is explicit about the B44/B50 application.

Our records don't give much beyond that basic identification. Since we don't have appearance history or additional catalog detail on this one, treat it as a straightforward crank nut and confirm the specifics against your engine before ordering.
Given it's called out as the "late" version, there was apparently an earlier version that differs from this one, so make sure you're matching the right one to your motor.
