A lack of a battery suggests this isn’t running? Not sure how the seller concluded this was the Jeepster’s predecessor (I suppose, technically, wagons proceeded Jeepsters, but this wagon was definitely post Jeepster). This wagon includes a gov plate.

“1959 Jeep Willy’s 4×4 Delivery Panel Wagon. Great restoration project for a piece of Americana. This is the predecessor of the Jeepster. Because this is the Delivery Panel Wagon model, the tailgate opens with two doors for easier access. Has a Ramsey Winch and wood paneling inside. Has the Super Hurricane Motor. Call for showing or more pictures”
