We think there are points of interest on each of these cars which you should try. The cars could return as soon as you have finished with them. We attach herewith sketches of the arrangement of each of these cars. The dimensions have been taken off the cars themselves - they may not agree with the drawing dimensions exactly. We have now seen your wire asking for a car with RRM. DES.60 scheme. We propose modifying the car fitted with the DES.60 to this arrangement. Hs.{Lord Ernest Hives - Chair} | ||
