| To BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} c. to Wd.{Mr Wood/Mr Whitehead} X5310 Hs{Lord Ernest Hives - Chair}2/L.11.6.29. 20 HP. 10 X 47 AXLE GEARS. X5310 X Now that we have increased the bore of the 20 HP., the prospect of using this lower gear ratio is very remote. There is a possibility that we may want to higher the ratio on the 20 HP. instead of lower it. In our opinion therefore these gears may as well be scrapped. Hs.{Lord Ernest Hives - Chair} | ||
