Here is a nice, fairly clean example of a Marx O gauge 6 inch 663 Pole Car.  This is cleaner than most of the cars of this type that I see up on eBay, but does have signs of playwear.  It has 4 stamped metal wheels on metal axles, and riveted tab and slot couplers, so this was likely in an electric train set.  The wooden pole load, the tiedown bar, and the springs are all REPRODUCTION parts, but are true approximations of the originals, and look good on the car!  Photos from all 6 sides, with a penny in the shots for size reference.  Priced to sell, with only actual USPS Ground Advantage or Priority shipping charged!
