The Rock Island vise had to weigh close to 100lbs. bolted to a sheet of 1/2 in. steel, which was bolted to a steel base, a steel wheel filled with concrete, and hanging on the back was the large electric motor, take an hour to break it down just to load.   Then the vise went for $45, #######, darn.   Spotted the antique drill press in his other shop, old, and was sorely tempted, but do not need a 4th drill press.   Even I don't see stuff like this around very often.
