| To RHC.{R. H. Coverley - Production Engineer} From Ha/Rm.{William Robotham - Chief Engineer} YS30. Ha/Rm.{William Robotham - Chief Engineer}6/MJ.22.7.31. EXHAUST SYSTEM - 19-G4. In view of the fact that this car is held up for radiator alterations, we should like to have the complete exhaust system to N.Sch.3287 fitted to this car. We believe you have already made a straight through down pipe from the manifold to the silencer and we should like to take this to France as well as the scheme with the small front expansion box. We should then test both out and select the better. Ha/Rm.{William Robotham - Chief Engineer} | ||
