Dear Sirs, Many thanks for your letter ref. WPR/DP. dated 8th. February, enclosing revised drawings of high crown pistons, in three bore sizes. We note that we may expect a further revised print showing your recommendations for reduction in weight. If this looks hopeful, we would like you to incorporate the modifications in a new core box, to produce the "high crown" piston recently decided upon. In the meantime, will you please supply - 36 pistons F.487. An order to cover these will follow. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
