My brother owned an original MK so I can tell you that's an original Midway cab with the 25" monitor in it. The cabinet is definitely a Midway cabinet, but it looks like the CPO is not original. Since we can't see the sides or the coindoor, I can't tell you exactly which Midway game it is.
Alot of games were put into that style of cab. Notice the wierd button configuration, though. It dooesn't look like an MK. The buttons are too close together vertically. That leads me to believe we're not even looking at an original control panel, not just the overlay. That looks almost like a modified Street Fighter layout. There's only 2 Midway games that I know of to use that layout - Killer Instinct and Killer Instinct 2. The original Killer Insinct used red t-molding, too.
