| R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} COPY Hs{Lord Ernest Hives - Chair}2/LG3.7.22. DYNAMO FOR 4-Goshawk-11. It will be a week or 10 days before we shall have a completed generator with built up mica commutator. Experiments are being made on the bench, bursting moulded commutators but we are not building any more machines of this type of commutator. Hs.{Lord Ernest Hives - Chair} | ||
