| X9410 To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to CJ. DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} R1/M16.10.24. RE. FRONT SPRINGS. X.2628 X.1331 X.9410 My idea of testing the exact strength and design of spring that we were going to use without insisting upon either make was that I understood it was difficult to obtain satisfactory Firth springs in time. Naturally I should prefer the exact strength, design and make, that we intended to fit. I therefore agree with Mr. Johnson, and only point out that Firths and Woodheads springs could be compared relatively on the bump test. Mr. Johnson will kindly decide to what circum- stances we shall bend i.e. (1) waiting for Firths or (2) testing Woodhead and carefully comparing - any-way we shall not be content unless Firths equal Woodheads on the bump test.
