Stern made eight games in those slim cabinets (Tut, Bagman, Super Bagman, Pooyan, Rescue, Minefield, Starjacker and Tazz-Mania), at one point I actually tracked all of them down and still have five of the eight. Nearly everyone is slightly different.
In addition to the different cabinet shapes, some have over/under coin doors, some the standard Stern two slot coin door.
