I have a piston manufactured by Mahle, part number 77P16 which was given to me about 30 years ago at the Cosworth plant in Northampton. Does anyone have an idea what engine it was used in?
If anyone from Cosworth is reading this, it has a serial number etched on it as well, so maybe (long shot considering the age) you'd be able to identify which car is was installed in?!
Edit: Mahle have confirmed my recollection that it was manufactured for an F1 car, but I'd love to know which one.
