X2748 X4224 The Works have recently supplied us with a set of Pistons with taper grinding on the sides. We have fitted these to an engine and run them, and the results are very good indeed. A standardisation has already been completed for this - we therefore recommend it to be adopted as soon as possible. Hs.{Lord Ernest Hives - Chair} | ||
