Actually, if I remember correctly, the data plate on the Enterprise at Darien Lake indicates that it was built by Heinz Fahtz, another of those German ride builders we've never heard of.
Schwarzkopf built smaller Enterprise rides particularly distinguished by the hinged tub roof...the side of the tub opens like the door on a DeLorean. But the one at Darien Lake has 16 tubs and a sliding door, just like the one at Adventure World.
The Huss Enterprise has 20 tubs on it and has a sliding door. And the Skylab has...er, I think it has 20 double tubs, a sliding door, and a lower age requirement.
