| x1583 Exptl. Dept. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}1/KW. 16th February, 1935. Messrs. C.C. Wakefield & Co.Ltd., Wakefield House, 30 & 32, Cheapside, London, E.C.2. Dear Sirs, Re "Hi-Press" Oil. Owing to the results we have so far obtained with this oil we should like to have some for our gearboxes with the same extreme pressure properties but of the viscosity of your CW Oil. The oil we are running now has the consistency of XXL but we understood from Mr. Massey that there is no difficulty in supplying a thinner oil. In that case will you please supply us with 5 gallons. Perhaps you would so name the new oil that it is not confused with the Hi-Press we have at present. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
