That is great /forums/images/graemlins/laugh.gif I have seen them on "Classic tractors" (RFDTV) and if I remember right they were designed to be the only vehicle you needed to take crops from the field and haul them straight to market /forums/images/graemlins/grin.gif Quite a decent road speed!
That was a 1939 Minneapolis Moline UDLX Comfortactor. THey also made one that had a similar cab and was a tricycle frontend for use as a Mail delivery machine in rural areas, I think most of them went to Colorado.
