This looks to be a Convertible DJ-3A body on a 4WD chassis or a DJ-3A chassis converted to 4WD. The serial number is 56337-10467, though the last digit is very hard to read, making the body from 1946.

“1st thing look up the zip code so you know where the item is located. If your not willing to come and get it or have someone haul it then please do not bother to proceed any farther. I can haul it but 1/2 down before moving and 1/2 down of haul fee.
From best i can find this is around a 1949 CJ-3, the motor, a overhead valve cylinder engine, we put in years ago but then just forgot about working on it. The tub is loose, the fender is off, one is missing. What you see in the pics is what you get, it is a project without a title. The jeep has the vin tag on the tub but is hard to read”
