| X5790 To Mx.{John H Maddocks - Chief Proving Officer} from EFC. EFC5/T29.9.28. WATFORD R.O.1. MAGNETOS. Referring to the R.O.1 magneto No.105629 which you recently submitted to us on account of faulty operation, resulting probably from too small a safety gap, we have tested this and agree that same is faulty. Will you arrange to obtain another magneto in place of this one as it is our intention to return this machine to the makers for their investigation. EFC. | ||
