Base on the motor and the year, I suspect this is a CJ-3A with a 3B body.

“1950 Willys Jeep: Good bones minimal rust, mechanically sound with original engine however previous owners may have used expired poultry to apply top coat paint. If you are a latte drinking hipster lacking calluses on your hands this vehicle may not be for you. This vehicle is for the guy who has shotgun shells in his dungaree pockets, dirt under his finger nails and may associate the term drive through dinner to the bugs collected in his teeth in route to a destination.
New items include: tires, hoses, 12 v system, alternator, gages, seats, steering wheel w/integrated horn, exhaust, turn indicators, shocks, brakes, etc.”
