I had a look at all the 'as found' images.
It's not as original as the blue one up above that Wes found, in that it has the engine from an equivalent 1939 one point five ton and the back body is either from a 1940 VF or a Chevrolet 1.5 ton. I'd guess that both were added during a 1944 army rebuild so it isn't exactly thrown together like a farmyard conversion.
David (the owner) paid a decent pile of money for it and hauled it home a thousand miles or so - it isn't going to be cheap but it is nice.
