| W/S. Sg.{Arthur F. Sidgreaves - MD} from Hs.{Lord Ernest Hives - Chair} 10-G-3 Hsl/LG20.9.28. X5410 X5770 Replying to Sgl4/M18.9.28. At the moment we do not wish to dispose of this car as it is the only 20 HP. covered car we have. The other 20 is rather an old type. We wish to use this car for comparative tests on springing. At the moment the new type 20 HP. G.4, the first of which is being used by R.{Sir Henry Royce}, is very poor for springing, decidedly worse than the standard car. This car will be used in conjunction with 10-G-3 to carry out springing tests so that we cannot part with this car at the moment. Hs.{Lord Ernest Hives - Chair} | ||
