| FROM R.{Sir Henry Royce} Copy to HS.{Lord Ernest Hives - Chair} R2/M26.10.29. ORIGINAL 25HP. RADIATOR. It is hoped that we shall be able to drop the bottom of the 25HP. radiator to give more area, and to improve the appearance. (DA.{Bernard Day - Chassis Design} is working on this.) I have since thought that with the hypoid back axle we could drop the line of transmission, even if only a little. This would result in the floor and the top edge of the frame being lower, and perhaps upswept at the front, and so lower the floor both at the front and back. This might be done at the same time as the improvements of reducing the diameter of the flywheel, and simplifying the clutch. R.{Sir Henry Royce} [Handwritten Annotation]: X5250 | ||
