| .6066 To Rm{William Robotham - Chief Engineer}/FD.{Frank Dodd - Bodies} from Rm{William Robotham - Chief Engineer}/Wst. Rm{William Robotham - Chief Engineer}/Wst.12/AP.11.12.36. CHASSIS 32-EX. We should be glad to have a report from you as soon as possible on the acoustic properties of the new Lucas horns mounted under the bonnet, as compared with the Mellotone horns mounted inside. We are anxious to know whether horns under the bonnet effectively move traffic and whether they are appreciably more noticeable inside the car than the horns mounted outside. We should also like particular notice taken of the horns when driving in heavy mist. Rm{William Robotham - Chief Engineer}/Wst. | ||
