| 118/1 11th March 1937. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}21/AP. The British Belting & Asbestos Ltd., 59 Southwark Street, LONDON S.E.1. For the attention of Mr.Sisman. Dear Sirs, We thank you for your letter of March 10th., and we note that your 'Halo V' has a lower soefficient of friction than Halo III, but as we have already ordered the latter it is unlikely that we will call for any 'Halo V' for some weeks. We regret that we had forgotten your wear measurement system, and note your estimate of the wear resistance of Halo III. and V.{VIENNA} Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
