| S/W. Rm.{William Robotham - Chief Engineer} 300 LE5/C/11.12.36. Re Phantom lll. I notice that there is a very pronounced drive groan on Phantom lll. at about 22-24 m.p.h. This is undoubtedly a very unpleasant feature. Have you got any scheme for overcoming this? If you are in London at any time I shall be pleased to take you out on a new car and shew it to you.
