I had a 1941 Army Jeep in the early 1990s. Before long I decided to sell it. After no buyers from my Auto Trader ad, I was given $800 (the same as I had paid) at a dealer on a trade for a 1986 Mazda RX7. Couple of weeks later I got a phone call from a guy in England wanting to know if I still had the Jeep. Turns out it was one of the prototypes delivered to the Army when they were deciding who would get the contract to build the original Jeep.
The stamped grill hadn't been created yet, so the prototypes had grills made of flat metal slats. Funny as I thought the original had been damaged and the one on it was home made.
