DIY-1945, I think you've also posted this on Practical Machinist. Candy Otto built fine machines. I have one that may be the same model as yours. This was was always flat belt driven but is not a line shaft machine--if you look closely, the boss for the electric motor mount is cast as part of the frame. It has a small footprint and takes up very little floor space. Not a great amount of value here as noted above by four.cycle, but a good useful machine, maybe $100-200 on Long Island where I'm located although you don't provide a location.
