Hs{Lord Ernest Hives - Chair} By Mx{John H Maddocks - Chief Proving Officer}10/T28.11.29. re Phantom II Exhaust Some time ago you agreed to delete the drain hole in the silencer, as was done on the Trials car 1-WJ, as this was found to decrease the tendency for "spitting" to occur. As the trouble is prevalent we should be glad if this modification could be put through. | ||
