I remember seeing a trhead with all the piston stamps of each different h22 piston but i cant seem to find it. I have what i believe to be (what was told to me by the seller) some type -s OS pistons but i dont have any part numbers just the piston stamp.

It reads:

AO
P5M


could someone please link me to that thread or clarify what pistons these actually are?

 

I have a set of Type-S pistons (OS .25 bore) and the stamps read: P5P...But I'll check again...

and the other side is stamped: HF1

P5P is Type S.
