UPDATE II: Marc noted the the rear of the vehicle is based on a Renault Juvaquatre. It just so happens this car is somewhat based on the German Opel, which Wally King used to create his Jeepster-like vehicle in Germany following WWII.

UPDATE: UndiscoveredClassics.com had some additional insights into this vehicle. I tried to learn more about Captain Richard C. Fitch of the Second Regiment Mechanized Cavalry Reserve, Los Angeles, but didn’t have much luck. I did learn he was a design engineer for the Army and was responsible for the MT Tug design (see below post). Below is a photo of how it looked in a newspaper.
=======================
Originally published March 2014: I wonder what ever happened to this prototype? Marc spotted this unusual photo. The vehicle doesn’t seem very jeep-like, except in its compact design and front clip similarity. It doesn’t appear it was four wheel drive.
The image was picked up and published by a couple newspapers. Below are links to Newspaper.com that show a small image of the page. The caption vary slightly:
1. The Amarillo Globe (Amarillo, Texas) March 18th, 1942, on Page 2
2. The Statesville Record and Landmark (Statesville, NC) March 16th, 1942, Page 4
