Here is a Marx O gauge 6 inch 552 Rock Island LIGHT BLUE gondola with red interior, white lettering and DARK BLUE details.  Marx put tons of 552 gondolas out in red, but far fewer in the two tone blue color scheme.   The car has normal playwear but should clean up a bit and looks good even now.  It has 4 stamped metal wheels on metal axles, and riveted tab and slot style couplers.   Photos from all 6 sides, with a yardstick in the shots for size reference.  Priced to sell, with only actual USPS Ground Advantage or Priority shipping charged!
