| X6058 PN. {Mr Northey} from EFC. {E. Fowler Clarke - Electrical Engineer} X6058 X.9712. EFC {E. Fowler Clarke - Electrical Engineer} 2/AD23.1.31. BATTERY IGNITION COILS. We thank you for your PN {Mr Northey} 4/PH21.1.31. A preliminary answer of a general nature to RL/M15.1.31 is in preparation in which the matter of sectionalised windings is referred to. We feel it would be looked upon as too expensive a construction for small car coils nevertheless it would probably be of interest to have names of manufacturers with whom we could communicate on the subject.
