| X6110. EFC. BY/RD2/W.12-11-30. Re :- Insulating Paper for Ignition Coils. We hand you herewith a sample of paper .00075" thick, supplied by the same sourse as the sample we obtained from Messrs. Lucas, and which gave such an excellent report. Will you please test this and let us know if the thinner paper continues to bear out the good qualities of its predecessor. In the meantime, we are asking the L.P.S. people to give us samples of wax-impregnated paper. BY/RD RECEIVED 12 NOV 1930 | ||
