Here is an operator grade American Flyer (by A. C. Gilbert Company) S gauge #911 Chesapeake & Ohio gondola.  It is black in color with white lettering and has the Pikemaster knuckle type couplers that Flyer used.  This car is in decent shape, BUT one step is broken off.  Look over the pics and judge for yourself.  Complete with all parts present and accounted for, and those couplers function.  Photos show the car from all 6 sides with a yardstick in the shots for size reference.  Priced fairly with only actual USPS Ground Advantage or Priority Mail shipping charged.
