| To WOR.{Arthur Wormald - General Works Manager} from Hs.{Lord Ernest Hives - Chair} X8430 Hsl/LG7.8.26. PHANTOM SIDE STEERING TUBE SPRINGS. X8450 X8430 Replying to BJ17/E5.8.26. R.{Sir Henry Royce} has already laid it down very definitely that his recommendation as regards dealing with existing cars is to fit the .940 worm and the weaker springs in the side steering tube. We agree that this is the best which can be done. On the other hand, we know we can make 50% or 60% improvement in the reduction of road shocks felt on the steering column by alteration to the side steering tube springs only. The Paris Depot, who hear much more about this trouble than we do in England, are satisfactorily dealing with customers complaints by alteration to the springs only. As regards the strength of springs to be used. It is now agreed that the Expl: Dept: original recommendation for fitting 1500 lbs. spring is the right one. Sales, who at first criticised these springs, have now agreed that they are the best compromise. See CWB5/LH{Mr Haworth}4.8.26. As far as the Expl: Dept: is concerned we have made all the tests we consider necessary on covered cars, we understand R.{Sir Henry Royce} is also satisfied. If Sales wish to carry out further tests they can easily be supplied with sets of springs and they can fit them on to any car they like and test them where they like.
