BSA PISTON B33 SHTROD 9.5+030

This one is a bit outside our usual Triumph lane. The catalog entry reads as a piston for a B33 application, oversized 030, with a compression note of 9.5. It's an isolated listing in our records with no other catalog rows or figure references to lean on, so we can't walk you through fitment specifics or which engine family it pairs with beyond what's printed here.
