DOING 10,000 MILES - X.5840. In agreement with reports while driving this car here, I also thought it was too lightly sprung at the back for France, and shock dampers were not effective enough. This is exactly the same conclusion we always come to - stiffer springs and more effective shock dampers for France than for England and USA. The best solution known to us at present is RR. hydraulic shock dampers on both axles of both models. Work hard and constantly until these are correctly adapted to each. I say RR. because Lovejoy are only one way, and cannot be effective enough without other defects, and they have not forced filling during suction. Are our patents sufficient and good, and all we can do? R.{Sir Henry Royce} | ||
