| HS {Lord Ernest Hives - Chair} x3900 ? To Wor. {Arthur Wormald - General Works Manager} from Sg. {Arthur F. Sidgreaves - MD} re Road Springs. Sg {Arthur F. Sidgreaves - MD} 13/E4.2.35 Copy to Hs. {Lord Ernest Hives - Chair} R.BY. When you have the Cadillac chassis up at Derby, I should very much like you to arrange for one of the back springs to be completely dismantled and examined from the point of view of how it is made. I was out on a Packard this week-end with conventional springing and it is a very beautifully sprung car. I do not believe that the Americans spend the £'s that we spend per spring in grinding, polishing, cadmium plating etc. etc., yet they get extraordinarily good results and it is with the object of trying to find out how they do it that I am suggesting that the Cadillac spring should be completely dismantled and examined and shown to Firth's. One wonders whether the English spring makers really know as much about it as the Americans. I know that in the ordinary way the American cars are too softly sprung for our liking but this is really a question of insufficient shock damping, which on the Packard existed in a controllable form, with the result that one could get a really excellent ride.
