Hi folks
I hope someone can help me as I have hit a minor snag.
I have realised that the drawings I have must be a slightly different (possibly older) version of the Kofferaufbau (Box Body) van type and on looking at the reference Marco and Frenchy gave me it gives different overall dimensions for the vehicle than the ones on the drawings.
My main problem is just the dimensions of the box in the photos. If I can get that right I can work around the rest. I tried to do some proportions from the pictures I have but the different picture angles and views are throwing me a lot so no two dimensions seem to work out.

Or maybe I am just thick
DOES ANYONE HAVE THE BASIC DIMENSIONS

Has anybody got one of these sitting outside their back door?
Hope you can help
Nige
