Nice, circa 1950s to 1960s era, O scale, kit built wood with some metal trim, reefer car, likely from Athearn, train car in the pictures. A large 10 3/8 inches long. Maybe useful for a little larger than O scale. Pretty worn and weathered with missing top center trim piece and missing one of the side metal doors, and brake wheel, lots of wear to the paint and cardboard siding as shown,  could be missing other small trim. Sold as shown.  Zoom in for details.
