Somehow there is a huge piece of the table missing? :-) Nothing some elbow grease, can of wd-40, deruster, spray gun and scrubbing brush won't fix though. I am going to cast a nice shiney new table and handle for it when I get the time. The major fault on it which makes it annoying to use is the down feed on it has lost it's spring and no longer returns when you let go of the handle. How is it arranged inside? Is there just a spring that pushing the quill back up?

Generally, they use a giant watch spring (coil spring) to apply torque to the pinion. There
certainly are other ways it has been done on some models. You may need to degunk some
of the works, or wind the spring one turn tighter.
