The ball return system inside should consist of wooden chutes, kinda like a gold sluice, that fit together like a jigsaw puzzle.
It has the ball release knob, which is kinda rare, especially if it still works the levers inside the table to open the gate on the ball return.
They used to put a bucket under the end of the ball box, pull a knob that tripped a lever or two back up in the middle of the table to release the balls into the bucket to be carried back up to the counter or to store away from the table.

Very cool table...
The market for great tables like this one isn't as strong as say two years ago, but I'd still have to search my soul long and hard before I'd let it go for $8,000.
We setup a Brunswick Reno a while back that was worth $25,000 easy, with all the original parts, accessories, balls, cues and new stuff as well.
Still one of my favorite tables of all time....
And just for the record that table of yours is so beautiful it SHOULD make someone's head hurt!!!lol
$15-20K should be around the right range unless there is stuff that we can't see that is wrong with the table.
