Further to our Mx{John H Maddocks - Chief Proving Officer}/McM5/T14.5.28, the above Magneto has now passed through test i.e. Unit test, 200 miles on road, and 2 gear quietening tests. It is quite a good magneto for noise. Will you please let us know what to do with both the EW.6. Magnetos Nos.100096/7. Satisfactory for starting up from cold.
