UPDATE: Price dropped to $3000.

(07/16/2018) Listed as a 1941, my best guess is that it is a CJ-3A.

“Have a 1941 willys flat fender jeep with a 225 Buick v6 motor, 4 speed Saginaw transmission and a Model 18 transfercase. The rear axle is a Dana 44 with a power lock, flanged axles and 538 gears. The front axle is a disc brake dana 44 with a Trac lock and 538 gears. Everything works, the tires have less than a 1000 miles on them and the front hitch is included. This jeep has literally been everywhere and has the scars to prove it. I’m asking $3500.”
