We cannot accept jacks on the axle for the above chassis, the inertia of the added parts to the unsprung weight is too great a handicap for both 'ride' and 'road holding' on a car capable of Bentley speeds. We must find a method of using a light weight jack as heretofore. Bentley 50 is another affair, and axle jacks for this are a reasonable proposition. BY.{R.W. Bailey - Chief Engineer} | ||
