Here is a pair of quite nice Marx O gauge silver tin lithographed Santa Fe solid lithographed window streamlined passenger cars.  There is a #3152 vista dome car, and a #3197 observation car.  Both cars are equipped with 8 stamped metal wheels on the earlier type E trucks with plastic overlays on the sides, and shorty metal tilt style couplers on the ends.  Both cars are the unlit solid window versions of the cars.  The cars are in decent condition, with some small areas of tarnish/corrosion.  The coach is in better shape than the observation.  I only washed with water, so perhaps a good cleaning will improve their appearance even more.  Photos show the cars from all 6 sides, plus a closeup of the drumhead on the rear of the observation (it is an original lithographed drumhead, which is frequently missing).  Priced to sell, with only actual shipping on the 2 pound package charged to the winner!
