| To Roy.{Sir Henry Royce} from EPC. (47)a EPC2/T20.11.28. FERRANTI AMMETER. With reference to the attached letter (copy kept) there is so far little further to report on this matter. The instrument is on an expl. car and has, up to the present, run 1090 miles. It will take some months to complete the 10,000 miles of running to which we subject all experimental items. We do not at the moment require any additional information or modifications. EPC. | ||
