| Da{Bernard Day - Chassis Design}, from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}3/AD4.4.32. We send you herewith drawing of the latest Buick gear box and also the Chrysler freewheel from the back of the gear box. We also send you the Stewart Warner booklet so that you can observe the details of construction of this servo. We agree that it somewhat remarkable that they are able to run their servo plates at propeller shaft speed without overheating but they assured me on this point. * We also send a complete description of the Cadillac free wheeling device as we know that you are interested in it. We have a complete set of the parts described here and can fit them up to a car if Sir Henry is sufficiently interested. We enclose a picture of the Cadillac gear box which may interest you. * This is being compiled and will follow later. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
