| To RHC {R. H. Coverley - Production Engineer} , _x5040_ Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 12/KW.12.10.34. Semi-Split Type Pistons. We recently sent some instructions through for semi-split pistons for the Bentley and 20/25 with modified grinding. E. {Mr Elliott - Chief Engineer} has now agreed that in view of the success of the Aerolite pistons we can drop the semi-split type, and we should therefore waste no more money on grinding tackle. Will you therefore please act accordingly. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
