I stumbled upon this unusual Willys creature at this prewarcar website.  I guess Wally Cohn wasn’t the only person trying to create a unique body on top of the Willys platform.

“2 of these willys mb were bodied in germany in 1945. one was destroyed, ended in hamburg probably beeing rebodied to an original jeep, so when i got that survivor i did not do the same mistake and put it on the road again. now it is one of a kind with all the original chassis, drivetrain, axles etc. even with the original data plate date of delivery nov.11, 1944 (author Bussinger Kfz)”
