Did you look under the intake for the letter?

You'll need a bore gauge to determine what size piston you require.
http://www.wossnerpistons.com/ Difference from A to B is 0.01mm, and so on from B to C etc |

The cylinder is marked E on the intake side, 2cm from bottom. Clearly, piston size is marked A-D, so cylinder is unmarked.
Using a bore-gauge tomorow. Typical that im in a hurry and get and unmarked cyl. Still have not answered my question thought. I still doesnt know what size A, B or D is. If I measure XX,96, still doesnt know what piston I need. Please clearify what size for example A piston or D piston are.

The clearance between the cylinder and the piston should be around 0,06mm!
Means, when measuring 72,00 on the cylinder the piston is 71,94!

If you take a look at Wossner's home page and select your engine size and year, they will show you what bore size pistons A B C will fit.
