Mostly asking out of pure curiosity. This has been for sale near(ish) me for a while. They're asking $100 which seems a little high unless it's something special.

The front looks like it says "Nishijin" and it looks like a model B machine. I don't own a model B to compare it to. But looking at pictures there are a couple extra "bumps" on the right side. Or maybe this one just has a plastic cover that's usually missing? What are those orange wires on the right going to? That seems like a weird way to route wires for a jackpot light. Or is that typical on a model B?
