| X7960 To C. From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Sn.{Mr Sanderson} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} 2/MJ.9.12.29. 21-EX. There are a number of features on this car with which we are not altogether satisfied. We are thinking of putting a new crankshaft in the engine with a low inertia slipper wheel and also doing some work on the steering and suspension of the car. We therefore propose to keep it a further ten days or so. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
