Looks like a Chicage Coin "Mini-Baseball" with a different face.
The Mini-Baseball came with a pedestal base, but it also had a wall mount bracket so you could hang it on the wall too. Game play is sort of like a pachinko, but you use skill with how you shoot the ball to guide it down the rollover lanes sort of like a pinball. Very reliable operation. We had one on the route back in the old days. All that I ever had to work on was jammed coin chute and dirty rollover switches.
Steve Young's Pinball Resource will have manuals/schematics for this.
