Mx{John H Maddocks - Chief Proving Officer}3/T.1.3.28. I see no objection at all to starting to use the EW.6 magnetos, sandwiching same in with the E.O.6 type, as and when each are quiet and available for use. There must certainly be a period when we are using both types of magnetos, as otherwise it would mean this Company or Norths paying for a large amount of costly scrap. BY.{R.W.
