One More Time! Until Next Time, Anyway...

I picked up another Vintage machine last night:

What really drew me to it is still a question to me. See if you agree.
Take a look at the center pocket here . The black wheel with Nishijin written in white has a split(?) at the top. I think the wheel splits apart during bonus rounds & the tire opens to let balls fall into the hole just at the bottom behind the wheel. Am I crazy or does anyone else see it this way?

Does it also look like when the ball falls into the tire, that it then "falls back out thru' either of the 2 holes below it to then fall into the pocket below that?? Unless there is a shelf piece missing I dont see how balls otherwise would go "into" the holes below the tire???
