1126 c. EJJ/DH.{D. Henderson - Showroom} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}3/MH.{M. Huckerby} 19th. January, 1939. Messrs. Hopkinsons Ltd., HUDDERSFIELD. Your Ref. 'RCA'E.4249. Dear Sirs, Thank you for your letter of 17/1/39. It is essential for our purposes that we have 1 lb. divisions on the pressure gauge. We could, however, achieve what we want with two gauges. One should read from 300-400 in 1 lb. stages, and the other from 0-100 in 1 lb. stages. They should both have the same thread for the pipe connection. Can you supply such gauges, and if so, at what price with 8" dials ? Yours faithfully, for ROLLS-ROYCE LTD. | ||
