BJ. X3854 R2/M30.3.26. FRONT SPRINGS X.3854 X.3803 X.5410 I do not consider BY's scheme would work in practice, but that we ought to test Woodheads scheme for rebound leaves, though even this might not give us any advantage over what we are doing, and good xx shock dampers which should be less harmful because more or less one way, any more constant and independent of lubrication. LEMOINE EXTRA LEAVES ON 10-G-3. This is our old practice, and good. This car was excellent and remarkably steady in front: the back seemed hardly damped enough. R.{Sir Henry Royce} | ||
