| X.4181c. To BY.{R.W. Bailey - Chief Engineer} from EFC. EFC1/T23.1.24. X.4181c - WATFORD E.O.6 MAGNETO FOR 20 HP. Reference EP{G. Eric Platford - Chief Quality Engineer}'s note EP{G. Eric Platford - Chief Quality Engineer}13/H7.1.24 complaining of contact breaker noisiness of these magnetos, we should like to know if you have taken any steps to obtain from the makers a standard of what they consider a satisfactory magneto from the point of view of noise. If so, we would like to make a comparison of this standard with three E.O.6 magnetos taken from production, which we have with us at the moment, having been loaned to us for the purpose of issuing the specification of production test, dated 27.12.23.
