Hello all! I recently picked up an early electric Heiwa. There's clearly a piece missing from the back that directs loosing balls to, well, I guess that's the question. I can see that there once was something attached, but currently, loosing balls just sort of fall out the back of the machine. I'm not optimistic I'd be able to find the actual original part, but I was hoping someone might have some reference pictures I can use to fabricate a solution. Whatever it ends up being will need to clear the jackpot lever and then hopefully deposit the balls in a tray. Anyone got some pictures of what this looked like originally? Here's the back, and the area where the piece is missing is within the blue square.
