| X6004 By {R.W. Bailey - Chief Engineer} /RD. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 5/AD24.9.29. 6004 X.8665. INTERMEDIATE OUTPUT S.S. DYNAMO. Further to our EFC {E. Fowler Clarke - Electrical Engineer} 1/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.
