Newbie Trying to Refurbish Pachinko - Help Appreciated

[life311]

Hi Panchinko Fans - I found this machine in my dad's garage (pics attached and embedded). It's been unused for awhile. No glass in front, no balls, and not sure what I need to replace/get it to function.

I did clean it - ha.

Anyone know what model this is?

Balls - I have none. Sounds like I need to buy 500. Was thinking of buying this? Thoughts? https://www.amazon.com/gp/offer-listing/B06X1FFBLM/ref=dp_olp_collectible_mbc?ie=UTF8&condition=collectible

Power - My dad said to buy 6V box battery to attach those loose cords to in back. Does that seem right?

Glass - I read a post here to get an 1/8" plexiglass and optional front glass. I don't know dimensions. Should I just go to a glass repair place?

The entire back/functioning- Honesty alert, I don't even know how to play this game or how it works, but I feel like a bottom part is missing. Can anyone tell from the photos.

Stand - It's on two pieces of wood on either side, but it doesn't feel sturdy and one front side is missing. Any thoughts on what to do for repair?

That was a lot. Any help would be awesome. I'm sure there are more things I need to know too that I didn't even ask about. Thanks!
