| To EFC. from E.{Mr Elliott - Chief Engineer} X.2048. E4/G8.10.19. RE IGNITION COIL AND BALLAST RESISTANCE. Referring to our memo E3/G27.8.19. in which we ask you to send us an R.R. Ballast Resistance, would you kindly now instead send a complete R.R. coil and ballast resistance as standardised, so that it can undergo a protracted test on the lighting engine we have down here.
