After looking at your new posted photo's this is what I think, I agree with P-feif that it is probably a modified Satan's hollow that has been cut near the monitor and control panel either due to damage or for the monitor I have seen case's of operator modification like this for monitors but it also has been cut to add ventilation covers probably for the monitor change and I also think why the 4 screws there are gone is since the wood looks to be replaced. I also think the operator converted the game to elevator action since Satan's hollow was pretty controversial for having Satan and demons
Also on other notes I find it kinda funny that the operator just put the elevator action marquee underneath the gladiator marquee
I think you're right. This cabinet is a frankencabinet. I think I'll just fix it up as is.
