| To RHU. X263 HS{Lord Ernest Hives - Chair}/Wym.{G. Harold Whyman - Experimental Manager}10/JH.16.9.36. E-23-AE - Exhaust System. Will you please arrange to fit the 4.750" dia. cast exhaust manifold to the above car, and a straight through downtake pipe in mild steel "Aluminized". We should like another exhaust system made up similar to the one which has been running about on this car, but made in production form, as the one on the car at present is only a test "mock-up".
