| EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/Ed.{J. L. Edwards}5/JH. 6th. March, 1939. Messrs. Dobbie McInnes & Clyde Ltd., 57, Bothwell Street, Glasgow. Dear Sirs, Will you please supply as soon as possible, six spare valve discs suitable for a 'C' type indicating unit. We should be very interested to know the material of these valves, and also if any alternatives are available which may not be so prone to oxidisation. An official order for the above is being passed through our order office. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
