[Kiwi912]

This came in a box of Mahle 911 Pistons & Cylinders (that I'm seeking help to identify on the 911BBS).

The story goes that a guy bought this set and then later returned them saying they were no longer needed. Ages later it was discovered that one of the 911P&C's had been removed to be replaced by this 912P&C. The guy at the checkout obviously didn't inspect the contents too closely before giving the refund!
I wouldn't want to have been him when the boss found out!!!

The piston has KS on top, Kolbenschmidt right?
But the cylinder has another mark that I can't decifer, any ideas?
