| 86113 Hs{Lord Ernest Hives - Chair}/Wat.3/MA. May 27th., 1933. The Telegraph Condenser Co.Ltd., Wales Farm Road, North Acton, London, W.3. Dear Sirs, We have received the special sample of impregnating wax you sent us sometime ago and we have now completed tests of the same. We find this wax to be immensely superior to ordinary paraffin wax and we should be glad to know if you would recommend this type of wax for the impregnation of coil winding when such windings are wound with enamel wire. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
