Attached is a complete description of the vacuum operated clutch on the Cadillac car. This is considered to be the best arrangement that has so far been produced in U.S.A. We have a complete set of these parts at Derby and can fit them to one of our cars if it is considered to be of sufficient interest. If Sales Dept. wish to try the vacuum clutch control, it is fitted to the latest Buick cars. Ha/Rm.{William Robotham - Chief Engineer} | ||
