| X6004 By/RD. from EFC. EFC5/AD24.9.29. 6004 X.8665. INTERMEDIATE OUTPUT S.S. DYNAMO. Further to our EFC1/AD23.9.29, owing to the slight discrepancy in the M angle, would you please instruct that we have the first armature for observation before the winding is put on so that our experimental shop can give us a check of the M angle in a way similar to that which they did previously.
