| W/S. Hn.{F. C. Honeyman - Retail orders} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X7230 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/KT.23.2.33. With reference to Hn{F. C. Honeyman - Retail orders}14/I/22.2.33. Attached herewith is a copy of EPL10/H22.2.33. which I think is interesting though there is not the least doubt that on a number of cars this procedure will not make the slightest difference. There are certain cases where it may reduce booming, and we want to find out whether they are a large proportion of new cars. In conjunction with JLE.{J. Lee Evans - Chassis Test Manager} perhaps you can help us get some information on this point. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
