Gottlieb Push-Over (Gottlieb, 1934) Questions

[Artvandalay]

I really hope someone can help me!!

I received this pinball machine for Xmas from my wife. I collect everything and she thought I would like this and I DO!!!!!! Looking to get some help, value, story, how to go about getting it back to original condition. It does work but needs a couple things tweaked internally. Someone unfortunately painted it. She got it from the original family so we are basically the second owners. Looking for info on how to get a hold of some of the badges, plates, etc....
I’m also wondering I noticed it has 2 NRA badges towards the top under the glass ( original??? )
Any info would be appreciated.

Pretty cool! I like the look of the marbles, but it's not clear to me if those are original or if it was designed for steel balls. Looks like IPDB (below) has some kind of opaque ball.

Google of course shows a lot of guides / sites that would probably help you with restoration:

They also have the billboard ad at IPDB:
