I'm pretty sure it was the Centuri one. I don't recall any elaborate graphics on the side.
I thought I had a picture of it somewhere, but I can't find it right off.
I picked up a game a couple of weeks ago and one of the cabs ended up being a converted D-Day. I couldn't figure out what it was until I found the tag inside with the name on it.
If anyone wants it and has a cab I can use in trade then they can have it. I got it for the monitor, but am thinking of converting it to a vertical machine to put a Pleiads or Phoenix into.
