I recently gained ownership of a pair of defunct cabs. After several weeks of cleaning and research, I'm still stumped as to what this originally was... When I got it, it had been outfitted with a Kid Niki conversion kit. I thought it might be an Asteroids Deluxe cabinet, but the dimensions don't work out according to another post on the forum, and the top of all of the AD cabs I've seen has a downward angle above the marquee art. Mine has a straight horizontal cut. I'm wondering if this may have been a different construction run, or a game with a similar style. Any help would be awesome!
