Cooper/ Gardner Denver AIRFEEDRILL
This drill is a series MM13, model 83501AB4, rated at 350 RPM, 1.25 hp., 700 lbs of thrust, with a 2 inch stroke.
New, never used but slightly abused before it was sold to me. One of the little (easily replaceable) hose barbs was broken off before I obtained it. Must have been a couple thousand dollars when it was purchased from Cooper, but this drill is not in production now.
