| X236. Hl. from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}10/KT.27.3.33. We thank you for your analysis of the Bentley piston which we handed to you. For record purposes we should be interested to have a figure for the tensile strength of the 10% zinc and 2% copper alloy at 300°C, compared with the correct alloy at the same temperature.
