| 1181 Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}4/NH. 31st. January 1938. The British Belting & Asbestos Ltd., Scandinavia Mills, Cleckheaton. For the attention of Mr.Sisman. Dear Sirs, Your material Halo 2L is giving satisfactory service as a servo lining; it seems less inclined to squeak than Halo 3L, in fact it has not squeaked at all yet. We are wondering if it would make a good brake lining. Can you describe its characteristics as compared to Halo 3L ? Yours faithfully, for ROLLS-ROYCE LTD. | ||
