Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X5460 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/ADS.9.32. R.R. PETROL PUMP ON THE 25 HP. When we get the R.R. semi-expanding carburetter we shall want a petrol pump on the 25 HP. A design has been made and detailed and we believe a crankcase casting is already in existence. We should like to have one of these crankcases available suitable for the large journal crankshaft, the crankcase eventually will be fitted to 19-GIV. We should be obliged if you would push this job forward. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
