| 1332 Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}12/MH.{M. Huckerby} Experimental Dept. 20th. June 1938. Messrs. Dunlop Rubber Co. Ltd., Fort Dunlop, Erdington, BIRMINGHAM. For the attention of Mr.H.E.Price. Dear Sirs, We are scheming a simpler arrangement for blowing up the tyre in the case where wire wheels have discs fitted to them. Obviously, the valve has to be in the part which protrudes through the disc. We are not certain of the exact dimensions of the interior of the ordinary Schrader valves. We shall be very grateful if you could send us blue prints showing the necessary details. Yours faithfully, for ROLLS-ROYCE LTD. | ||
