X9910 To Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} SECRET. DA{Bernard Day - Chassis Design}5/M21.E.24. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. X.9910 X.9941. Referring to your Hs{Lord Ernest Hives - Chair}5/LG18.6.24., it is quite true that the trip on the countershaft might be dispensed with. It provides a safeguard in case the servo lever should seize or become stiff, but it is very unlikely that this would happen. Could you experimentally fit up a car with this shaft made solid? It would enable the scheme to be rather simplified as a single lever can be used for the rod to the servo, and the rod to the differential, giving us a little more room which we are very glad of.
