| X4383 To RHC {R. H. Coverley - Production Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 8/T11.10.23. X.4383 - GOSHAWK DYNAMO EXPERIMENTS. We are re-handing to you herewith dynamo 562, upon which you carried out the modifications instructed in By {R.W. Bailey - Chief Engineer} /Ds/1/ML15.8.23, consisting of easing off the trailing edges of all the poles. In accordance with our previous instructions EFC {E. Fowler Clarke - Electrical Engineer} 2/T25.9.23, will you kindly have this again put on 3 GII for comparison as regards the noise phenomenon with itself in the previous condition. The B dynamo removed from 3GII to make place for it should be returned to us, contrary to our previous instruction (5) in the above mentioned note, which previous instruction should now be cancelled.
