Educated guesses (I can't find the manual online, and I assume you don't have one either, or you wouldn't be asking this)

It looks like the saucer (not an outhole, an outhole feeds the trough, and on modern machines, there's only the one below the flippers) is missing ball guides of some sort. There's not much else that would make sense to be there.

Organ is missing a wide scoop, which would shunt balls into the hole (right now, they'd bash into the shaft that the moving part of the organ rotates on, which would be a Bad Thing). You can even see the broken off ends of the scoop on each side.

Good luck getting the parts - I suspect it's going to be a battle to find those...

Me and Techno knew it was like this when i bought it.. It suck's to make the shot to the Organ and have the ball to pop-back out.. ( Organ is missing a wide scoop ) Wam bam,, Thank you Maam !! Get-r Done Techno ..

Yeah, i saw that ball diverter. Not sure where it goes, but not there. I wouldn't want to play it without the scoop on there, either - i'd be afraid of bending the shaft, thus breaking another unobtainable part.
