UPDATE: **SOLD** Was $1200.

Colin did some due diligence and determined that this is likely a former airport baggage conveyor DJ. Here’s a very similar conveyor DJ from the 3B page.

Here’s what Colin deduced: The mounts on the front frame rails are in a position where the front conveyor supports can be mounted.

The rear platform for the conveyor is attached to the rear corner of the tub on those DJ3As and on the sides of the CJ3B as well (see the CJ-3B page).  It would preclude the rear taillights, and  rear fuel filler that is standard on the DJ3A, but one photo of the DJ3A with the North Central Convair 500 shows the fuel fill tube low on the right rear corner, and the rear wheel opening is modified just like the one on 20796 (See the CJ-3B page for pics side and rearish. 

Also, the right rear corner of the tub is modified to clear the conveyor.I suspect the large holes in the rear panels helped support the bracing for the rear platform and also carried the hydraulic lines and controls for on the ground operation.  The Line lock was for the brakes and the chrome handle on the left side of the dash were no doubt for the governor.  The emergency brake T- handle was moved to a location where the driver could set it, otherwise it would have been under the conveyor apparatus.

“1950’s model DJ3A Military Willys Jeep DJ3A. Body in great shape, nearly rust free, have engine and transmission, 2 windshields, most of the major parts are there. Needs restoration or used for parts. Too many projects already so decided to move on.”
