| x7560 E.{Mr Elliott - Chief Engineer} from By/Cgh.{W Clough} c. BJ. Hs.{Lord Ernest Hives - Chair} By/Cgh{W Clough}8/G.6.10.28. SS.{S. Smith} WIRING DIAGRAM. X.7560. X.7730. X.7740. With reference to E1/M3.10.28 and print of LeC.2595 showing technical wiring diagram, we have shown this to EFC. and it is considered that the diagram is quite in order except that a body lighting switch is not shown. We also notice that you have shown a dimming switch for the headlamps, but we are not sure whether it is intended to have fixed or dipping headlamps. Upon receipt of your revised original drawing we will arrange for a drawing to be made on white paper in indian ink and coloured for reproduction, which will be submitted to you in due course.
