| To R & E.{Mr Elliott - Chief Engineer} from EFC. c. CJ. & PN.{Mr Northey} c. EY. EP.{G. Eric Platford - Chief Quality Engineer} WOR.{Arthur Wormald - General Works Manager} RE ELECTRICAL WORK. X4383 Answering your M1/M20.9.23, with regard to Goshawk dynamos and their brush gear, it is our experience that with the very special care in workmanship and experimental test that these receive in the Expl. Dept. the running of the commutator and brushes is reasonably satisfactory. This applies both to machines we have run on bench tests and various machines run on experimental cars, the total mileage of which is now very considerable. We are constantly experimenting, however, to discover further and further means of rendering these more satisfactory under ordinary manufacturing conditions on production than at present. At the moment we feel that these machines require an unwarrantable amount of attention on production test, also that there is insufficient inspection of these electrical parts in the various stages and less proportionally than is undertaken in the case of mechanical parts. x9660 with regard to the E.A.C. dynamo - this is well in hand and we should receive the first experimental machine for test early next week.
