| BY. {R.W. Bailey - Chief Engineer} from R. {Sir Henry Royce} c. to BJ. Wor. {Arthur Wormald - General Works Manager} c. to Hs. {Lord Ernest Hives - Chair} 44469 R1/M19.11.28. NITRIFYING HARDENING. X.4469 X.3822 X.7060 X.4003 X.7090 The first things to try in this are the 'SS {S. Smith} ', and aero engine, valve gear followers, and camshaft. The thing it seems least suitable for is the sliding change gear, and piston pins. The SS. {S. Smith} cam followers should be put in hand at once. It may be necessary to make them in this material, and anyway they should be better. R, | ||
