| Y7791 EFC. from Mx.{John H Maddocks - Chief Proving Officer} Mx{John H Maddocks - Chief Proving Officer}7/T9.11.28 re EW.6. Magneto - H.T.Brush Squeaks [STAMP: RECEIVED 8 NOV] With reference to your memo EFC2/T7.11.28. We have sent into the Stores for return to the Makers EW.6. Magneto No.113996. This machine knocks badly, also the brushes squeak very badly. It has been run on the Unit Test Bed, Dynamometer and road, and has done about 350 miles altogether. If you wish to test this magneto before it is despatched to the Makers you will doubtless obtain it from the Stores. Mx{John H Maddocks - Chief Proving Officer} | ||
