| X.7791 . To Mx.{John H Maddocks - Chief Proving Officer} from EFC. c. Ev.{Ivan Evernden - coachwork} EFC4/T23.3.28. WATFORD EW.6. MAGNETOS. We understand from Mr. Daykin that recently you had an EW6 magneto which failed to start the engine immediately on first trial, although purporting to have been duly production tested. A case of this sort we regard as a particular case for our investigation, because if it has passed the production test, it certainly should be O.K. on the car, or if not, our production test requires altering, and we must have an opportunity of investigation with a view to such alteration.
