The engraving on the cylinder say’s Chaumers Bessermer. This engine runs great on compressed air. Check out the video below. This engine is heavy, mainly because of the base. I figure it weighs 30 pounds. I would be willing to detatch the engine from the base if requested and just send the engine if you request. The base of this steam engine measures 18 Inches by 12 Inches and the engine is about 6 inches high. The drive wheel is about 6 inches tall and 1/2 an inch thick. The engine runs great on air. Here is a video of the engine running. If you live in the St. Louis Area and just want to pick it up.
