BHB was the original maker of AMC pistons. There should be a 6 digit part no. stamped in also, which will identify it. Cheers, Don.

I wouldn't mind one of them to go with my SH cams i haven't fitted yet. Anyone making them? I've got to keep up with the Velo boys!!

Ahhh. I looked for that in the spares lists but missed it. The list only states "high compression". Cheers, Don.
