L1A1. The pommel and cross piece are rivetted on later. They didn't refurbish for us but they did supply new. They also used these blades to make new No5 bayonets for Sterling.

To be perfectly honest, pressed steel grips for our No5 bayonets would have made perfect sense in a production engineering world where commonality = cheapness. Alas, the L1 series blade part is totally different to the No5 type blade
