Seller has removed a layer of blue paint which revealed olive drab. Otherwise, I would have thought this was an Air Force jeep. Maybe used by the Army, then. the Air Force?

“1953 M38A1 Willys Jeep. It is pretty much original though the electrical system has been converted to 12 volts. The brakes have been rebuilt and the tires are new. The canvas top is laying in the back on the floor. The exterior and interior were painted blue and the seats are upholstered in blue. I was going to freshen up the exterior paint. The blue easily came off with sanding leaving the original olive drab and markings. To restore it back to olive drab will take more time and energy then I have so it is for sale. Asking $6000.”
