| 85992. S/W. Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey} re- 20/25 h.p. Special Touring Saloon 20-G4 Cx{Major Len W. Cox - Advertising Manager}1/KW26.11.31. Sg{Arthur F. Sidgreaves - MD} has passed to me your Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}1/MJ23.11.31. We are very much interested in knowing that we shall be able to have this car at a comparatively early date. In order that we may understand when we should be able to demonstrate with it and talk about its features, would you please let me know what the main differences are between 20-G4 and 18-G4. We shall only be able to use 20-G4 when chassis of that type are able to be offered to the Public, but we have reason to believe that when that is so we ought to be able to sell quite a few of them.
