Dear Mrs. Hall, I apologise for not acknowledging the brake material. We have now tested this and the attached blue print shows the results. The material is less susceptible to heat than some we are at present using, but is not so good as the best material which we have so far tested. Yours sincerely, FOR ROLLS-ROYCE LIMITED. | ||
