S&DJR 6-wheeled brake third - drawing by PJS c1969

One of the drawings I made prior to carving up Triang GWR clerestory coaches back in the late 1960s. It is probably better to call them general arrangement drawings. The panel sizes are almost certainly related to the GWR models' dimensions, although the layouts were taken from the original Derby photos and Atthill's Picture History of the S&DJR. That was about the only reference book I had, apart from Casserley's British Joint Lines.
