| 1229 Experimental Dept. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}10/MH.{M. Huckerby} 21st. June 1938. The Vacuum Oil Co. Ltd., Caxton House, Westminster, LONDON, S.W.1. For the attention of Mr.O.T.Jones. Dear Sirs, Thank you for your letter of June 20th. We should like to take advantage of your offer of more inhibitor treated Mobiloil A on an engine to determine the effect on piston scuffing. We have asked our Order Office to send you an order for five gallons and should be glad if you would send us four more gallons. We understood you to say, and should like to be sure that no harm can accrue from leaving this oil in a new engine after running in, even although the car stands at the coachbuilders for a considerable time. Yours faithfully, for ROLLS-ROYCE LTD. | ||
