| Y4-P19.10.23. contd. - 2 - (5) In regard to the Dynamo, it is proposed to use the E.A.C.1. machine with a 3rd Brush Control, which we have already instructed. It is urgent therefore that the Exp. Dept. should push forward with this. (6) D.{John DeLooze - Company Secretary} Dept. should note that the changeover switch being designed by W.W. will be supplied for both E.A.C.2. and the 20HP. In the case of the former it will have to be on the Instrument Board, that is, easily accessible - in the case of the latter it will be on the engine side of the Dashboard somewhere. We should not worry ourselves at the moment about applying the changeover switch to the 20HP. BY.{R.W. Bailey - Chief Engineer} | ||
