| BY {R.W. Bailey - Chief Engineer} /CGH. {W Clough} from E. {Mr Elliott - Chief Engineer} c. BJ. EFC. {E. Fowler Clarke - Electrical Engineer} X7740 E1/M1.9.28. PHANTOM GREEN LIGHT SCHEME. X4040. Referring to the above, R. {Sir Henry Royce} is agreeable that the green lamp itself should be fed from a separate source as suggested by EFC. {E. Fowler Clarke - Electrical Engineer} , which requires an extra terminal on the green lamp unit. Perhaps you would submit a proposed scheme shewing this alteration as we have our hands full at the moment with other matters. The technical wiring diagram also requires some attention.
