With regard to the order, we are arranging for this to be sent covering four pairs of concave dial instruments complete with drives. The outline dimensions will be similar to the first pair of this type recently received, i.e., to D.75203. The speedometer revs-per-mile calibration to "798" and the drives to DB.{Donald Bastow - Suspensions}1060. We are returning the nickel plated drive for modification to DB.{Donald Bastow - Suspensions}1060. With regard to the clock, we intend in future to fit this as a separate unit. Yours faithfully, for ROLLS-ROYCE LTD. | ||
