| X1725 X8350 To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}5/LG19.3.23. Herewith acceleration curve as requested per attached note. Really far the best thing to do is to take the customer out in the car fitted with the 14-tooth axle. The difference in one tooth axle ratio can easily be more than counterbalanced by loss of engine tune. These figures should be used with discretion. Please return tracings and two copies of blue prints for our file. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
