Wanted : NOS Sachs 1st O/S Piston/Rings

[slvrbrdfxr]

Hi all,
I'm looking for a NOS Mahle 54.5mm 1st O/S piston with rings for an alloy cylinder so that I can finish the top end on my MCB Enduro project. Thought I had one stashed away but must have used it on another engine. Anyone have one they are willing to part with ?? Let me know. Thanks !!
