| X.4261. To hs. {Lord Ernest Hives - Chair} from R. {Sir Henry Royce} R1/M/13.12.22. BUSHES FOR SPRINGS ON 20 HP. Referring to your Hs {Lord Ernest Hives - Chair} 3/LG8.12.22., can we at the same time adopt a bush with flanges driven in from each end, so as to provide a large and hard surface to resist end wear. Would you please confirm that the hole in the top spring leaf has worn .015 to .200 oval ( see 8th. line of your memo.) or should it be .015 to .020". ? R. {Sir Henry Royce} | ||
