| 86017 Experimental Department 9th December 1936. Rm {William Robotham - Chief Engineer} /Wst.14/AP. Bakelite Ltd., 68 Victoria Street, LONDON S.W.1. Dear Sirs, Referring to your letter of the 17th ultimo., reference GAJ/AS., we beg to say that we have found "Halowax" unsuitable for ignition coil impregnation due to its high inductivity. If you have a wax to offer us which has approximately the same inductivity as paraffin wax, we should be interested in carrying out further tests. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
