| To BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X5310 Hs{Lord Ernest Hives - Chair}3/LG11.10.28. 20 HP. 10 X 47 GEARS. Although it has been agreed not to use the 10 x 47 gears as standard, we recommend that any gears which have been produced with this ratio should not be scrapped. We are working all the time with the object of trying to produce an engine which will run fast without fuss and noise, and any improvement we get enables us to use lower ratio and a better performance. We therefore recommend that these gears are kept in stock and the matter is reviewed every 6 or 12 months. Hs.{Lord Ernest Hives - Chair} | ||
