| To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to BJ. Y/5300 R2/M28.11.27. 20 HP. X.5300 X.4538 Will you try the effect of reducing the weight of the flywheel and clutch. This appears to be about the only part on this chassis which we can hope to gain any real advantage in weight, outside the smaller wheels and shorter hubs. E.{Mr Elliott - Chief Engineer} will soon be working at the new head for the engine, when we hope to gain a little in weight and power. R.{Sir Henry Royce} | ||
