| +8950 S/W for Hs.{Lord Ernest Hives - Chair} Re: Chassis 29-CL. ------ With reference to our former conversations on the question of strength of side steering tube springs and shock dampers with viscosity effect, which it had been agreed should be tried on the above chassis, I should like to be able to receive the necessary parts for this during the next fourteen days in order that I may be able to superintend personally the question of their fitting. Is it possible for you to arrange delivery within that time? It is understood that you will be able to let me have a set of 2000 lbs. per inch side steering tube springs and also some washers, which will have the effect of even stiffer springs in the side steering tube and also a set of the new hydraulic shock dampers with viscosity effect. In connection with the damper and also with the scheme of springing which it is proposed should be fitted to this car, i.e., the Continental type of stiffer springs, I note on page 2 of your HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}2/LG5728 (40/50 H.P. steering) that you say 12-EX was most comfortable on the run down to Le CanadelHenry Royce's French residence this year, but impossible - apparently due to its stiff rear springs - at low speeds on the coast road. Was this car fitted with these Continental type stiff springs and if so, in view of this report, do you still consider that they are an improvement on our standard type of springs for general all-round purposes in an open touring car abroad, as compared with the standard type of springing fitted with the hydraulic dampers with viscosity effect?
