| To LHS{Lord Herbert Scott} from Sg.{Arthur F. Sidgreaves - MD} Copy to C. Cx.{Major Len W. Cox - Advertising Manager} re Ventilation on Closed Coachwork. What conclusions have we come to in regard to the so-called draughtless ventilation as brought out by General Motors and Quicktho? After fairly extensive use of my car I have come to the conclusion that it is not draughtless. Taking the front seat, the position appears to be that, if the driver has his open, it is draughtless for him but draughty for his passenger and vice versa as the stream of air is shot on to the wind screen and across on to the seat on the other side. Have we any practical experience yet of the Ford scheme? At present I am rather inclined to agree with Sclater Booth who said last summer that the other scheme of glass louvres over the doors was as good as anything known to date. Sg.{Arthur F.
