| To BY/RD. X842 X6027 EFC3/T5.5.27. X14132 X8821 In regard to the use of punched armature plates for 40/50 starter motor, or for either of the other two motors, the standardisation of this is not a question of test, because sometime back we reported that motors thus built are equally efficient, but it is a question of manufacture convenience and costs. Therefore we look upon it as in the hands of your Dept. to say whether a standardisation sheet is necessary can be put through. EFC. | ||
