Here is a really nice example of the O gauge Louis Marx and Company $5590 New York Central operating crane car.  The car is black with white lettering and has a diecast base and plastic cab and boom.  Complete and in nice shape, this example does not have the frequently seen chipping around the ladder and the front of the cab from boom movement (you can see these critical areas in closeup photos.    The car is equipped with 8 diecast metal wheels on metal axles and has the plastic overlay style type F trucks with plastic tilt type couplers on both ends.  Photos from all 6 sides, with a yardstick in the shots for size reference, plus angled shots to show both cab sides to evaluate the lettering, one shot from above with the crane pivoted to evaluate the diecast base, and those shots of the critical areas.  Priced reasonably, with only actual USPS Ground Advantage or Priority Mail shipping on the 2 pound package charged to the winner!
