| -2- For future design work we would point out the desirability of making provision for the rear silencer to be mounted as far back in the frame as possible for the reduction of exhaust noises. On our present P.III car we are prevented from going back another 4 or 5 inches by the hand brake rope being situated in front of the rear axle. Rm{William Robotham - Chief Engineer}/G.H. Whyman. | ||
