| X5060. RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}11/MA. 8.11.32. J.2 ENGINE. We are now satisfied with the automatic adjustment tappets, except that we want some of the square wire return springs which you believe have been held up for lack of material. We should like to hand the engine over to you for fitting the 3 1/2 bore liners in the pistons, and could be getting some experience as to the power output of this while we are waiting for the new camshaft and induction pipe.
