I don't notice any splatter speckle over the paint, which I'd expect to see if it was a factory paint job. It was nice that the repainter took the time to take the legs off, and even got creative with the drop shadow stars, that's a lot more effort and attention to detail than I'd expect.
The original paint may still be underneath and salvageable if they used a latex paint you can scrape off.
Does the game have the big jukebox coin mech in it? I only just learned from a Clay video that the oversized Williams cabinets were designed around the Seeburg multi-denomination mech.
