On enlargement and re-examination of the photo I think you are correct about the door hinge location and the water recover tank. Plus that little item at the top rear of the door is in the correct location for the door latch handle. Which would make it a Pattern 13.

A higher resolution version of the photo would show more detail.

Whats your guess 2 or 4 wheel drive? Flat line of the front axle would seem to me to indicate 2.

Interesting puzzle Keith.

Cheers Phil
