| To Hy. {Tom Haldenby - Plant Engineer} from R. {Sir Henry Royce} X4333 c. to Wor. {Arthur Wormald - General Works Manager} c. to EFC. {E. Fowler Clarke - Electrical Engineer} c. to Hs. {Lord Ernest Hives - Chair} R4/M7.6.22. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) - DYNAMO BRUSHES. Referring to Hy {Tom Haldenby - Plant Engineer} 14/P8.5.22., EFC. {E. Fowler Clarke - Electrical Engineer} should not send pure experiments to France to disgrace the lot of us, but it has turned out a fortunate disaster, as it burst the commutator quick, and has so saved us making many by a scheme which has proved unsafe.
