| -2- RB.{R. Bowen}G/WH. 20.7.34. (1) Bonded asbestos brake liners to overcome ineffective brakes after car has been washed. (2) Brake equalising shaft with spherical bearings. This is a works request to reduce cost. (3) Sump drain plug to give increased ground clearance. (4) Front brake drums with bolts instead of studs. (5) Peregrine Gearbox. (6) Thermostat with modified leverage. (7) Forged steel clutch pressure plate. (8) Harrison type radiator matrix. (9) Modified front axle control. (10) Nickel gasket joint to cylinder head. (11) Drilled connecting rods. These are all points which we are anxious to get experience with and to test out, so that unless we hear to the contrary we shall start this car running as many miles per day as possible as soon as we have received the new bearing for the rear axle.
