This is a #18326 Penn Central jade green caboose with white lettering.  This is the caboose which was a match for the Penn Central diesels, although Marx also used it in sets with steam engines (*which is funny, as the Penn Central did not run any steam!).  This one is complete and in nice shape.  Has the 8 stamped metal wheels on metal axles, and plastic tilt couplers on both ends, as it should.  Light tarnish on the wheels and axles. Photos show the car from all 6 sides, with a penny in the shots for size reference (it is O gauge, runs on Marx 3 rail train track, which is pretty much the same size as Lionel O-27).  Priced to sell, with only actual USPS Ground Advantage or Priority shipping cost charged to the winner!
