| To Wd.{Mr Wood/Mr Whitehead} from EFC. X1109 EFC3/T3.3.22. X.1109 - IMPREGNATING VARNISHES. It is considered desirable to obtain experimentally say, 2 gallons of "Elo" impregnating varnish, as we have a report from Messrs. Lucas' that they consider it is the best they have tried for the impregnation of armature coils. Would you, therefore, kindly have ordered up 2 gallons of this for these tests. It might also be better for our ignition coils, possibly doing away with the slight greening effect which we have at present. EFC. | ||
