| EFC. X7701 BY10/G.11.1.28. IGNITION COIL AND CONDENSER. -------------------------- X. 7701 X 18710 We have obtained samples of an English made paper impregnated with paraffin wax, and I would like to have EFC's views on the paper in question as to its suitability for use in the above parts, and for comparison with our present standard paper. If EFC. is satisfied that its insulation properties are as good as the present standard then I would suggest we make up three ignition coils and three condensers to be run by EFC. experimentally on the bench and on cars to try out this particular material.
