| 566 To Rm.{William Robotham - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} Copy to Hs.{Lord Ernest Hives - Chair}E. re GAE-20, with Anti-rolling Rod Sg{Arthur F. Sidgreaves - MD}10/E11.1.37 Cx.{Major Len W. Cox - Advertising Manager} and I made a very careful test of this car on Friday with a standard 20/25 with a similar size and weight of body. We were driven over a certain route with a good many corners in it on both cars by the same driver at the same speed. We also conducted the same test over a piece of rather bad road in the London area. We came to the conclusion that to the occupants of the back seat there was no material benefit but the driver said GAE-20 was better for him than the standard. In actual fact we came to the conclusion that over bad roads you were thrown about rather more on GAE-20 than on the other car. So far, therefore, as the 'old ladies' type of car is concerned, we see no advantage in this scheme but it might be better for the owner driver type of body. When we mentioned about this test, you said that we perhaps ought to send both cars up to Derby (or you send a man to London) to change over the front springs and anti-roll device from one car to the other and then repeat the test. Iam not sure, however, whether this is really worth while. You might let me have your views on this latter point and the general aspect of the matter can in any case be discussed at the chassis conference on Wednesday the 20th. Sg.{Arthur F.
