We are recommending to R.{Sir Henry Royce} that the exhaust pipe be extended to the rear cross member to make the possibility of this still less likely. With reference to the use of a rubber support at the centre of the subframe instead of the present rigid one we would be glad if Exp. Dept. would give us their latest views. At one time we understood that they considered marked improvement in the smoothness of the car was made by this change. We agree that if this can be confirmed we ought to attempt to bring the change in as standard as soon as possible, and we have mentioned the matter to CX.{Major Len W. Cox - Advertising Manager} intimating that such a change is not unlikely to be asked for. Da{Bernard Day - Chassis Design}/Ev.{Ivan Evernden - coachwork} | ||
