This Marathon® Oil Operating Oil Derrick is brand new. The small parts are sealed in the plastic bags, so we couldn't install them to show in the picture. Includes the bubble tube (simulates oil being pumped), 3-oil drums, hook-up wires,  switch and instructions. The base measures 10" X 5-3/4" and the tower is 14-3/4" tall. The base and tower are made out of metal. This is a great operating accessory that adds excitement and action to your layout. For O and O-27 gauge trains.
