| -2- Contd. Both brush settings are shown angularly on the brush setting diagram sent out with our report on E.A.C. dynamo output. With reference to R's suggestions contained in FL/M23.2.24 of making the 20 HP. dynamo 1" longer in the active parts, from our experience of this having been done on the Lucas E.575 machine, we should say that it will only go 40% of the way towards what we want for E.A.C.3.
