| EY. FROM E.{Mr Elliott - Chief Engineer} C. to WDR. HS.{Lord Ernest Hives - Chair} MX.{John H Maddocks - Chief Proving Officer} re. LONGER EXPERIMENTAL PISTONS FOR P. 2. ORIGINAL 20-1-31 X70940. We are sending you herewith LeC/2861. shewing the illustrations of various pistons compared, xxx supplied by MX.{John H Maddocks - Chief Proving Officer}, traced for record purposes. A print is attached to MX{John H Maddocks - Chief Proving Officer}'s copy of this memo. In reply to HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}1/MJ14131., we think that the bearing surface might be tried on the lines of the RRAL pistons - i.e. starting at the same width as P. 2. at the top of the skirt but expanding more rapidly.
