| To Bx. from Da. {Bernard Day - Chassis Design} [Handwritten Signature] X15310 Da. {Bernard Day - Chassis Design} 1/MP.7.12.33. c. [redacted] Hs. {Lord Ernest Hives - Chair} J.3. with separate gearbox. In order to complete the instructions for this car, we have made N. Sch's 3898/9 (herewith) showing the rear brake differential made from existing parts and modified only to provide the new swivel bearings and for direct operation to 4 brakes, so that a mechanical system of brakes can be fitted up should we decide not to try the adopted hydraulic system on this car.
