6010 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/RC.{R. Childs}9/JH. 12th. May, 1939. Mr. C.S.Steadman, Messrs. John Marston Ltd., WOLVERHAMPTON. Dear Steadman, Enclosed is an unconventional wiring diagram of your switchboard arrangements, I have had to rely on my memory so that it may not exactly match up, however, the electric circuit is the same. I have made diagramatic sketches to simplify the reading of the circuit. With regard to exhaust flanges, Edwards will bring them down with him next week. Trusting that you are keeping well and your new work is proving interesting. Yours sincerely, | ||
