UPDATE: Still Available.
The seller of this believes this to be one of the six M-38 pilot vehicles, also known as MC-38s: http://www.cj3a.info/sibling/m38/pilot.html …. However, after looking at the jeep, it has been modified to such an extent that even if it was one of the pilot models, there’s very little left of it. That said, I can see nothing that identifies it as an early model: 1) Serial number of MC 10149 is too late (serial number on data plates); 2) No full-floating axles (pilots had the WWII rear axles); 3) No battery box (battery box lid hinges were on the sides of the pilot vehicles); 4) wrong windshield setup … the list goes on.
