| X8664 To By/Cgh.{W Clough} from EFC. c. Hs{Lord Ernest Hives - Chair}/CEP. EFC2/T19.5.28. Herewith we hand to you late standard 40/50 H.P. dynamo CH.85 (unmodified). This is the machine we have selected in accordance with your request, as a suitable one for modification for higher output at the higher speeds. Perhaps you will arrange for this modification to be made by Mr. Brock, after which the machine should be returned to us for confirmatory test. Will Hs{Lord Ernest Hives - Chair}/CEP. please arrange for crediting this Dept. with this machine, which will ultimately be used to pass on to one of the customers who requires a high output at the higher speeds. It was suggested that we should arrange a second one like this because of the time it will take to get back the machine replaced by the first dynamo so modified. EFC. | ||
