| To BY.{R.W. Bailey - Chief Engineer} From Hs.{Lord Ernest Hives - Chair} c. to E.{Mr Elliott - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} c. to Roy.{Sir Henry Royce} c. to Sft.{Mr Swift} X4584. X4027. PEREGRINE MATERIAL. The following is a list of the parts which we consider are safe to go ahead with :- (1) Crankcase. There is a possibility of the bosses for the controls being modified if we alter the carburetter. (2) Cylinder liners. In R.R. cast iron. (3) Crankshaft. (4) Engine Gears. This is a very important point. The Works should satisfy themselves that they can consistently produce quiet engine gears, as it is out of the question to pull the Peregrine down to do anything to the engine gears. (5) Water Pump. (6) Oil Pump. (7) Slipper Wheel. (8) Cylinder Head. This will be the turbulent type. We believe E.{Mr Elliott - Chief Engineer} may alter the angle of the plugs in the two centre cylinders to clear the modified induction pipe. (9) Valves and Springs. Large size inlet valve. (10) Rockers & Tappets, Push Rods. (11) Camshaft. (12) Frame, Cross members, Dumb irons. (13) Front axle pivots, steering arms. (14) Rear axle complete. We have complained of one or two noisy rear axles so this is a point which should be well considered on the first cars. (15) Radiator. Marston matrix. (16) Hubs and Wheels. | ||
