Hi David,
according to the book on Werner Stengel, the Dreier
Looping had its debut in 1984 at the Hannover Schützenfest.
The amount is said to have been 13.000.000 DM (more than 6.500.000 Euro).
I will check later on the date when the Dreier was sold to Malaysia (Sunway Lagoon), where it operated as a pink coloured ride.
EDIT:
According to a short article the Dreier
Looping had its debut on the 29.06.1984 at the Hannover Schützenfest.
Its final german fair was in September/October of 1996 at the Kramermarkt in Oldenburg.
When the Olympia-
Looping became Barths new flagship the Dreier
Looping began operation at smaller fairs, in some cases at places where there had not been a ride of that size before, so it became a npvelty for the second time. The Dreier travelled in those days fairs like:
Mannheim, Aschaffenburg, Augsburg, Straubing, Bad Kreuznach, Recklinghausen and others.
