This is a Marx O gauge AT&SF (Santa Fe) work caboose in tuscan brown with white lettering.  It comes on the later type F trucks, which had the later style of plastic overlays on them and came with diecast metal wheels.  This one is complete and in fairly nice shape EXCEPT that the little black plastic brakewheel on the rear deck is broken off and missing (Robert Grossman sells repros - Google him if you need Marx parts).  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!
