They also had some (very very few, like probably single digits) duramolds for Sinistar. And there's a rumor of a red duramold. Don't know of any other games to use a duramold.
I have an interesting (to me at least) tidbit on the Williams duramold cabinet. A buddy of mine that worked for Williams in the pinball line (until they got rid of their pinball line) said that the company that actually made the mold and made the duramold cabinets called Williams several years later to ask them what they wanted to do with the mold. Williams said they wouldn't be using it anymore. The company didn't want the huge thing taking up space at their company anymore either, so they drove it over to Williams (unannounced) and unloaded it on Williams' loading dock.
The thing was huge, like 3 times the size of the cabinet. Williams didn't want it either, so they moved it over to the dumpster (never even entered the building). Was gone at next garbage pick up. That's one piece that will NEVER be reproduced!
