| Copy. X8797 EFC. MX{John H Maddocks - Chief Proving Officer}/RCMB/T.26.4.27. re Watford EO.6. Type Magneto with enclosed armature tunnel. In reply to your EFC4/T.25.4.27. we are not yet in a position to make a complete report on these magnetos. So far one has failed during test, the complaint being make and break noisy, and misfiring at high speed. The other three are so far satisfactory but have not yet completed a routine test. We will report later on these. MX{John H Maddocks - Chief Proving Officer}/MCM. | ||
