It looks to be a pretty early one.

“I have a collection of 1946 VEC CJ2A Jeep parts for restoration or just parts. I was going to restore this but I have an aircraft restoration project that is more demanding of my time.
Parts include: Rolling chassis, (full floating rear axle), with tub, 4 like new 600×16 military NDT tires, engine, transmission/transfer case, radiator, rear driveshaft, drivers seat frame, non-VEC windshield frame, tailgate, hood, front fenders and grill.
Missing parts: Front drive shaft, exhaust system, fuel tank, VEC windshield frame, passenger seat frame and both rear axles.
The tub is interesting in that there is and opening around the steering column for the column shift linkage it also has the cover and mounting holes that look original for a floor shift. The trans I got with it is a top loader T90 floor shift.
There is the usual rust in the floors, toolbox and hat channels.”
