Big air compressor id??

[oddave715]

Who made the big air compressor that is mounted on a farm wagon type trailer? I know someone with one and I can't remember who made it or model number. It is powered by a 6v detroit. I keep thinking it is a sullair but I'm not sure and my searches are turning up pretty much nothing on this machine.

Ingersoll Rand and Schramm come to mind.

Sullivan, LeRoi and Atlas Copco to name some more. Those are all screw type compressors.
