| X 4079 a To EP.{G. Eric Platford - Chief Quality Engineer} from EFC. EFC4/TS.8.3.22. X.4079.- RE B IGNITION COIL+ We should be glad if you would let us have back for experimental purposes the one of the two original B coils, which we handed to you some months ago. These two coils are particularly good and we are anxious to dismantle one to ascertain the construction, but we need the one which is at present in our hands as a standard of performance. EFC. | ||
