It looks like it has had some small changes, but otherwise appears stock.

“1950 CJ3A civilian Jeep, runs and drives like a champ! All original drivetrain, however it has been converted to 12v GM, and it has had rust issues repaired, but it’s a pretty solid little Jeep. The original flat head 4, as well as the rest if the drivetrain is in very good condition and the same can be said of the brakes, and tires…even the heater works! Clear title and comes with tow bar.”
