| 1256 (Experimental Dept.) Rm{William Robotham - Chief Engineer}/Mthal/R.{Sir Henry Royce} 10th November, 1936. The Light Production Co.,Ltd., 60/66 Rochester Row, Westminster, LONDON. S.W.1. For the attention of Mr. C.H. Brooks. Dear Sirs, We are considering standardising the high pressure "D" type scraper rings giving 32 lbs square inch wall pressure, and in order to complete the standardisation sheet we should be glad if you could supply us with the following information:- (1) What is the specification of the iron and what treatment is given. (2) En value. (3) Increase in price, if any. These points have been raised by our Drawing Office in order that they can make the necessary alteration on the drawing and for record purposes, since the ring dimensions are exactly the same as standard. Yours faithfully, For ROLLS-ROYCE LTD. | ||
