| RG. {Mr Rowledge} from R. {Sir Henry Royce} Hs. {Lord Ernest Hives - Chair} c. to BJ. Wor. {Arthur Wormald - General Works Manager} BY. {R.W. Bailey - Chief Engineer} +4021 R1/M3.11.27. AERO MAGNETO DRIVE. X.4017 X.4021 Have there been any failures with the solid drive; if not we ought to use it. Would there not be less risk with the Watford, because of the M. {Mr Moon / Mr Moore} of I. being lower, (only half). You will remember that the Watford was used in all the high speed Napiers that were successful in the Schnieder Trophy Race, and that the Thomson-Houston failed at our high speeds.
