Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X634 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/MJ. 21.8.29. It is highly probable that we shall shortly standardise the lower inertia slipper wheel on the S.S. car. This is to LEC 2462 and 2526. In view of this fact we think that at least one of the crankshafts with the larger pins should be prepared to take this slipper wheel.
