| To RHC.{R. H. Coverley - Production Engineer} From Ha/Rm.{William Robotham - Chief Engineer} Ha/Rm.{William Robotham - Chief Engineer}6/MJ.30.6.31. SILENCER FOR 19-G4. The present 25 HP. silencer loses a lot of power. W.H. have given us an improved silencer M.Sch.3287. The main dimensions have been inserted in the attached blue print. We want to use a 40/50 fishtail with this exhaust system. We should like to have this silencer available so that we can try it on 19-G4 with a view to getting it on this car, if it is at all promising. If we do use this silencer we could arrange to incorporate the existing type of sliding joint. Ha/Rm.{William Robotham - Chief Engineer} | ||
