| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} HS.{Lord Ernest Hives - Chair} X3806 DA{Bernard Day - Chassis Design}2/M10.5.28. NEXT 10,000 MILES PHANTOM. 12-EX. X. 8940c X. 3806 X. 7350 With reference to the centralised chassis lubrication on this car, we have a scheme nearly complete which we shall send you in the course of a day or two. This modification will be required to be carried out before the car starts again. It is also necessary to substitute the serrated wearing pad for the rear spring attachment to axle instead of the present rollers, to avoid the necessity of lubrication. The scheme of this will be sent to you in the course of a day or two. DA.{Bernard Day - Chassis Design} | ||
