UPDATE: This may be an M-201 (at the very least it has some M-201 parts). Thanks to Gaston for pointing it out.
John shared this auction for an MB rebuilt in Europe, along with a trailer.

“This Willys MB is said to have been refurbished in Europe and was imported to the United States before it was purchased by the current owner in 2017. The truck is finished in olive drab green with US Army–style graphics, and power comes from a 134ci “Go-Devil” flathead inline-four paired with a three-speed manual gearbox and a dual-range transfer case. Equipment includes 16″ steel wheels, military tires, a rear-mounted spare, turn signals, a folding windshield, a tan soft top, a rear pintle hitch, pioneer tools, a jerrycan, seats with tan canvas cushions, a dash-mounted rifle holder, and radio equipment. The accompanying single-axle utility trailer is equipped with taillights, a canvas top panel, and troop-style seating with tan cushions. This Willys MB and trailer are now offered by the seller on behalf of the current owner with canvas doors and side panels, an inoperable rifle, and Arizona titles for both the Willys and the trailer.”
