The serial number puts this as a very early 1948. This had quite the bumper/tow-bar setup. I’m guessing the rear rack might have been used also as a top?

“This is a 1946 or so Willys CJ2A. Serial number 149435. It has sat forever.. And much of the time in a creek bed, judging by the sand underneath. I got most of it off by pressure washer, but it needs more. Much more. Really do not know much about it as I got it in a package deal with a lot of other stuff. The body is rough and tumble but other than a rust out by drivers door, is not too bad in the rust department. The passenger flat metal floor has same rust holes.The engine , well for that matter ,the axles,wheels,tranny,transfer case,hubs, and all do do not move now either. So this is either for parts or for a major rebuild. Bill of sale only”
