AND SILVER WRAITH I. EXHAUST SYSTEM. Please receive herewith :- E.CD.1392 Front Silencer and Rear Intermediate Pipe. Silver Dawn I. and Silver Wraith I. The exhaust systems for these two chassis are generally similar to the B.V. system, except for the longer rear intermediate pipes to suit the different lengths of wheelbase, and the tail pipes which are different to suit the longer rear road springs. The new rear intermediate pipes are shown on E.CD.1392 and the new tail pipes will be shown on a later design. The exhaust manifold, downtake pipe, front silencer and the rear silencer are exactly the same as for B.V. All the holes in the chassis frame for the exhaust system are the same as for the B.V. chassis, and we shall endeavour to reduce the alterations to the frame to a minimum when adapting the 6 and 8 cylinder C.I. engines to these chassis. Will you please detail and instruct for the experimental cars. DA.{Bernard Day - Chassis Design} | ||
