| BY. {R.W. Bailey - Chief Engineer} Hs. {Lord Ernest Hives - Chair} from R. {Sir Henry Royce} RG. {Mr Rowledge} c. to BJ. Wor. {Arthur Wormald - General Works Manager} 4290 R4/M22.11.27. VALVE SPRINGS X. 2993 X. 290 Is it to be understood that our valve steels are to be as specified in HL2/EA18.11.27., which specification and steel should have a distinguishing number or letter? We should like more comparative fatigue figures (Stanton) to be taken of this material, and others for comparison, R. {Sir Henry Royce} | ||
