What Mahle Pistons do I have

[930rsr]

I have a set of brand new Mahle Pistons I bought back a while ago. They were stated to be 3.5, 10.3 to 1 pistons. I bought all the items to build a 50mm PMO motor, now after years of sitting on the parts I need to know what I have. The Mahle piston cylinder has the code: 95ZN1++A3W6. (the last six could be an 8 but I believe it is a 6.
