| To. Rm.{William Robotham - Chief Engineer} 200a. CHATEAUROUX 6/.18.3.38. 6.B.IV.- BENTLEY. Throttle Spring. The reversed throttle spring was omitted from the 10,000 miles report. This was effective in preventing the wide variations in idling speed experienced on previous Bentleys and in service, and should be recommended for standardisation. ------------ Rm{William Robotham - Chief Engineer}/IMW.{Ivan M.
