Here’s an interesting article published in the May 1953 issue of Popular Mechanics. I don’t remember running across one of these. Interesting that they chose to use a VEC CJ-2A rather than a later model jeep. This issue also includes an introduction and comparison between the M-38A1 and the Mighty Mite.
