Shaft of Terror: Who really built it?

http://www.rcdb.com/installationdetail1481.htm

RCDB states that some dude named Ronald Bussink designed it, not Giovanola. I find it hard to belive, as we all have been beliveing it was Giovanola. I guess if it isn't Giovanola's then they have a track record of 3, not 4.

Now, at Cobra Roll, there are computer generated images of the ride. Does anyone know if these are Giovanola's pics? If they are, then does it verify 100% that Giovanola designed the ride?

Hey, SFGAm management, can I buy a couple cages of Sky Whirl?

Werner Stengel (spelling?) also designed most of Giovanola's rides, as well as many B&Ms, Schwarzkopfs, etc... Giovanola still built it as far as I know.
