Swindell} Rm{William Robotham - Chief Engineer}5/R.28.10.38. With reference to the attached report, we cannot fit two S.U's to the Wraith. We could, however, fit a Duplex Stromberg Carburetter. We do not see why, if we could get a satisfactory induction system the Duplex Carburetter should not give us much the same results as the two S.U.'s. We believe this is the reason why it is being fitted by Hudson. We would, therefore, like you to persevere with the Duplex Stromberg on the 4-port system. Rm.{William Robotham - Chief Engineer} | ||
