[QUOTE=Another item of note, the early GS bodies appear to be wooden with metal framing and the later bodies were metal sided with what appears to be wooden metal framed front and tailgate. More coming to light!

Pete, I think this is not a principle as I have an early WOT8 with round vents which had a metal sided body with wooden tailgate, same as the last surviving WOT8 in the UK which has the scoop air vents. You can see late WOT6s with both wooden and metal bodies. The workshop trucks had wooden body. In my quess there were more producers of the GS bodies.
