This huge old Walker Turner D.P. is for sale 45 miles from me for $250. PM me if you want the link. I have nothing to do with this sale, but it looks like a really. H.D. drill press.
Looks like a radial arm drill press. You can adjust how far out from the column the head is, and set the head on an angle. I've never seen one like that before, though. They usually just have a round ram.
