| 1258 EXPERIMENTAL DEPARTMENT. RM{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}7/JH. 29th. August, 1939. The Light Production Co.Ltd., 60/66 Rochester Row, Westminster Row.S.W.1. For the attention of Mr.S.H.Brooks. Dear Sirs, We are in receipt of your letter dated Aug. 25th. and appreciate your suggestions regarding the heat flow from the crown causing the hard bedding at the top of the skirt. If possible it would be a good opportunity to incorporate your suggested modifications (including the slightly increased taper grinding) on the 14 pistons ordered in our letter dated 22.8.39. We note that you are giving consideration to the reduction in weight of this piston. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
