Allan Swinden} Rm.{William Robotham - Chief Engineer}29/ML.14.6.40. UNDER BONNET TEMPERATURE - RIPPLE. Surely the low under bonnet temperature on the Ripple which is so detrimental to satisfactory carburation, can be overcome by fitting a deeper matrix of less frontal area. We have asked Ev.{Ivan Evernden - coachwork} to look into the question of doing this without spoiling the rationalisation of radiators and shall be glad if you will let me have your recommendations on the subject.
