| To By. {R.W. Bailey - Chief Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} c. By {R.W. Bailey - Chief Engineer} /Ds. X.4333 EFC {E. Fowler Clarke - Electrical Engineer} 1/T1.11.22. X.4333 - DYNAMO BRUSHES Further to our EFC {E. Fowler Clarke - Electrical Engineer} 4/T30.10.22, the Elec. Prod. Dept. now report to us that the Le Carbone dynamo brushes themselves vary in width, even as much as .020". This suggests somewhere lack of inspection, and also some inefficiency on the part of the makers. Perhaps you will kindly look into this matter, as it is most important that the fit of the brushes in the holders should be right. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
