| 66079 By/RD. From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.3/MA.10.11.33. PUNCHED PLATES ON 40/50-MOTOR. Regarding our telephone conversation re. the above upon reconsidering the matter we think it advisable not to attempt punched plates yet in view of the difficulty of the parallel slot which as you point out would reduce our average iron section slightly at the root of the armature teeth.
