I don't believe there has been a count but not very many black cabinet games slipped out from the factory (same with blue cabinet Time Line's). I have a black cabinet MGoW and really like the game. I've swapped in a NOS playfield, NOS plastic set, NOS instruction cards, NOS drop targets, converted it to 7 digit displays with dip switch setting for free play, converted to LED's, added a earphone jack with volume control and converted the backglass to mount up like BH. It plays crazy wicked and is very difficult to beat.
