⁣Check out this 1920's or so Curtis Air Compressor. There are more pics on my website: http://www.flamingsteel.com Picked this one up on Craigslist. Ran like a top when I got it and still runs but the belt tracks off now. The guy I got it off pumped it up to 40psi and two weeks after getting it home it still had that pressure. I don't quite figure out the middle pulley? I added the extra pipe in order for it to hold a plate glass top. I don't have the glass top here.
