I need the details reproduce the Jennings Improved Sportsman ball return board that goes under the playfield in the cabinet. I note there are two 1/4" holes in the cabinet sides near the rear along with a groove/slot in the rear of the cabinet.

There is an large cast aluminum receiver that the board would drop the playfield balls for feeding back to the ball lifter.

Note again this is the Improved version of the Jennings Sportsman sometimes referred to as the "deluxe."

The picture included is NOT the improved version is an example of the kind of thing I am looking for. Some interior pictures of an Improved
version would be nice, especially if I could comprehend how the board is fixed to the interior sides. TIA!

Let me add a picture of my machine with the cast ball catcher that is at the front of the machine. The ball return board will fit at the base, bottom of the aluminum ball catcher so that the release mech for the balls will permit the balls to be fed to the ball lifter.
