We were alarmed to find that between 80 and 90 M.P.H. the speedometer had a nasty period and we would like your assurance that this period will not cause damage to the instrument in the long run. (3) Concealment of Movement. We consider a big improvement in the appearance of the instrument could be effected if the dial plate completely concealed the movement as in other instruments and clocks. Will you kindly give these matters your consideration and inform us accordingly. Yours faithfully, For Rolls-Royce Ltd. | ||
