I concur with David's comment regarding the rectangular vs. square opening in the rear of the roof. It does not appear to be original. I also believe this truck should have come with an observation hatch (square or round). If you look closely at one of Hanno's other pictures of the roof it appears that the upper portion has been welded in which would explain the lack of a hatch or hatch opening. It also explains the correct reinforcement ribbing for the roof. My two cents.
