I just saw on the forum that someone wanted a set of D-type Cooper pistons, and I knew I had a set.
Fished it out and bugger me down!,3 pistons are at +020 the 4th is +030...had them since the 70's bought the set from a German.
Never trust them!
They are Kolben pistons and a full set of rings to go with them. I also have (somewhere) 8 neoprene buttons to replace the circlips.
The set for £150 ONO

If someone really wanted these they could spin the 030 down and regroove the ring slots...not a hard job on a lathe. then just re-gap the rings

Got a set of those Kolben Schmidt +20 D tops in my 998 Cooper.
