Here is an O gauge Marx 0-4-0 battery powered (DC) sheetmetal steam engine with a plastic boilerfront and tender!  This one has a battery powered DC motor and runs in both directions fine.  The tender included is a #551 New York Central 6 inch black 4 wheel tender with white lettering and gray details.  It is equipped with 4 plastic wheels on metal axles and has the punched sliding tab and slot type couplers.  The prior owner "embellished" the engine with silver paint on the drive wheels and black paint on the boilerfront.  Photos show the engine and tender from all 6 sides, with a penny in the shots for size reference, plus an underside motor shot, and a shot inside where the batteries would go to show it is clean.  The video shows the engine working - please note that since I did not have any D cell batteries around, I used the DC power from an old HO transformer to power the motor when taken out of the engine (just touched the two terminals that would come into contact with the batteries).  Priced to sell, with only actual USPS Ground Advantage or Priority Mail shipping on the 1 1/2 pound package charged!
