This is a great vintage handmade wooden oil derrick! Most likely a piece made for a train display. I purchased it at an auction in rural Somerset County, PA, at which a large toy train collection was sold. 15 1/2 inches by 5 3/4 inches by 14 1/4 inches tall. The turning handle works the pumping mechanism. Could use a better cleaning than I have given it. As you can see some it's coming apart a little as it has aged and one roof piece comes off. It's in great condition for its age, however, and will display beautifully. Very solid. A great piece for your display or collection! Questions welcome. Shipping outside the U.S. only through eBay's global shipping program.
