Yes, it is an old air compressor trailer forgot to take a tape measure too run some #s. Pretty set on picking it up for next to nothing. The bottom is open I'm guessing for air flow to the compressor I was told it had an Lincoln motor. Looking to change the hubs out and get trailer brakes. I've been collecting some parts got a 60 gal square tank that might fit down the middle. Excited and can't wait stay tuned but it will be a slow build..lol
