Derk, Jordan, thanks for your input.
All of the photos on this thread were made near the very end or after WW2. It may have been some sort of prototype/ in theatre conversion which wasn't very well documented by the CMHQ?
PS: This one was new to me, I found it captioned "Ernest Wood sitting on his Jeep in Holland, March, 1945".
