| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} X8300 DA{Bernard Day - Chassis Design}2/ML2.9.27. PHANTOM CLUTCH. NEXT 10,000 MILES TEST CAR. X.8300 X.8940b. Herewith we send N.sch.2465 shewing the serrated coupling inside the clutch, which R.{Sir Henry Royce} wishes fitted to the next 10,000 miles car. This replaces the original design LeC.2394. It will be seen that new top and bottom halves of the clutch pit are called for, but the crankshaft and the remaining parts of the clutch are unaltered.
