| To Hs. {Lord Ernest Hives - Chair} from R. {Sir Henry Royce} c. to CJ. BY. {R.W. Bailey - Chief Engineer} c. to E. {Mr Elliott - Chief Engineer} Da. {Bernard Day - Chassis Design} X4254 R2/M31.1.23. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. UNIVERSAL JOINTS X. 4254. Replying to your Hs {Lord Ernest Hives - Chair} 3/LG29.1.23., we regret we cannot do more than make the joints oil retaining, and dirt excluding. They ought to be O.K. for 10,000 miles, then it would not be too much for the parts to be refilled with grease, i.e. once a year. R. {Sir Henry Royce} | ||
