UPDATE II: Another of these surfaced in 2019.
(12/18/2016) Rudy just purchased this rare and unusual O.C. Szekely-built Ford powered four wheel drive APU. It’s got a an Szekely badge and an O.E. Szekely stamped transmission. I don’t recognize the transfercase, which falls to the driver’s side rather than passenger side.
Thanks to some careful research, Rudy discovered that this vehicle was one of eight deliver to the military on August 25th, 1953. Specifically, “”The vehicle is a specially built two passenger 4X4 truck powered by a FORD eight cylinder engine. . . . A generator mounting chassis, located between the seats, supports the two generators and generator drives” and the “transmission that incorporates the transfer case is designed to transfer engine power to the generator drive”. O. E. Szekely dropped off eight of these vehicles to a shipping service on August 25th, 1953.”
