| X6142 RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.3/KT. 2.9.32. 40/50 VOLTAGE CONTROL DYNAMO. Will you please produce for us as soon as possible a further 40/50 dynamo with the control brush removed, and the machine converted to a plain shunt dynamo, similar to the one fitted to 19-EX. We require this for further experiments in connection with the proposed standardisation of this voltage controlled system. Hs{Lord Ernest Hives - Chair}/Wst. | ||
