| -2- Rm.{William Robotham - Chief Engineer}1/JMS. 23.5.40. 6. We suggest that this method of installing together with a roof or whipsocket aerial be given a trial, and from it we will be able to see more clearly to many advantages. Yours sincerely, [Faint Stamped Text:] M.O. Dept. General Motors Building THORNTON DEPT. OFFICE P.S. [Handwritten annotation:] Dr. OH LETTS YOUR [Strikethrough] Serial No.95 - Davis Steering Gear and Oil Pump. [Strikethrough] The information you give us on good oil pumps is of great interest. [Strikethrough] The Booster we do not understand, but it is nice to know that such a thing is in existence so that we can take advantage of it if we need it. [Strikethrough] Hydraulic controls are, of course, of direct interest in marine and aviation work, and your notes on accumulator are of great interest. The one you describe certainly seems to be permanently pressure type. | ||
