| Mx.{John H Maddocks - Chief Proving Officer} To KAX. from EFC. X8793 EFC3/T11.2.28. We are handing you Lucas magneto 54B which is one of the pair recently brought up-to-date by Messrs. Lucas, one of which is fitted with wipe distributor and the other with a jump spark distributor. The one we are sending has a jump spark distributor and if it would be convenient to you to try this out for noise and low and high speed running on one of your test cars, we should very much like to know your impression.
