That thing is freakin' amazing, a little work of mechanical art. An actual piston powered air pump. Probably performs pretty well once it's cleaned up & has a belt. Even if you can't get it going, it would look good on the mantle all polished & shiny.

It's for sure built well still works just needs a new belt
