| (2) We have looked carefully into the question of the improved suspension of the gearbox, but we find that it will delay matters too much to wait for this, so we are completing the drawing exactly as the present Phantom, and including the present fabric coupling, so that there is no change to the frame (except the drilling,) the back or front axle, gearbox, torque tube, and starter. There is no change to the engine but there is 1½" to be added to the intermediate shaft between the engine and gearbox. We shall not wait for the new front axle as we fear it would delay the chassis, but the present front axle in its lightest form will be fitted. There is a new arrangement of cross member to go under the radiator, and also the radiator itself is being slightly modified and improved from anything we have at the present. It is a parallel radiator with integral shutters and the full length of matrix tube. There is a sine qua non that it must not exceed 6¼" in depth. DA.{Bernard Day - Chassis Design} is preparing a drawing. R.{Sir Henry Royce} [Stamp: RECEIVED 19 OCT 1928 2941] | ||
