yeah the A and B are just slight differences in sizes to help the assemblers at Stihl pick the best piston for the jugView attachment 456531 @Definitive Dave
Mine has a b stamped. Just sizing right? what is the aa circle?
The A over A nonsense I was spouting relates to coin collecting where a double strike on a coin can turn a normal coin into a Uber coin even in not perfect condition.
If such a coin had double or triple other mint created markings it would add a zero at least
