Antique Vintage Air Compressor Pump Hit Miss Steam Punk This is an antique/vintage air compressor pump. It works like it was bought brand new. Wheel spins freely. I hooked it up to a hanging motor/belt mount I use for my ball mill, and it works very well. Previous owner used an oil solution to prevent rust in the inside. Wish I would have known that before spinning it ;) The wheel is a 12" wheel. It is rather heavy, as you can imagine for cast iron, so shipping isn't going to be cheap. I would say it weighs a good 50 lbs. I will be mounting this on a board for easier handling as well. Do what you will to it when you receive it. Beautiful compressor pump. Email me with any questions or concerns. Thank you.
