| TO HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} ORIGINAL SECRET DA{Bernard Day - Chassis Design}5/M21. 6. 24. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. x.9910 x9941 Referring to your HS{Lord Ernest Hives - Chair}5/LG18624., 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 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.
