Bailey - Chief Engineer} from Rm.{William Robotham - Chief Engineer} c.Da.{Bernard Day - Chassis Design} c.Mx.{John H Maddocks - Chief Proving Officer} Rm{William Robotham - Chief Engineer}8/R.17.11.37. With reference to the requests for carburetter tests to improve petrol consumption and startability, we attach some consumption figures which show the results we are obtaining. We think it perfectly fair to assume that a customer should get between 12½ to 13½ m.p.g. with the new carburetter setting and the use of the new overdrive gear. You will observe that we are giving Sales a brief summary of this report which they may like to use for propaganda purposes. Rm.{William Robotham - Chief Engineer} | ||
