GOSHAWK - DYNAMO BRUSHES. Referring to Hy{Tom Haldenby - Plant Engineer}14/P8.5.22., EFC. 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.
