We send you herewith samples of waxed paper which we normally use in our Ignition Coils,and also samples of a plain paper which has been wound into a standard Coil and impregnated with wax. You will see that the wax has thoroughly saturated the paper and,upon examination,even to the innermost layers the wax was thoroughly in. Would you please say if this second paper is equal to that which is waxed before winding. BY {R.W. Bailey - Chief Engineer} /RD. | ||
