Thank you, it is a very nice piece, though it does require a little strengthening around the base to support the cardboard a little better. It wasn't cheap for it's time, about 35 pound back then. I guess it will be a mystery for the ages.
Edit:
Finally found it, I managed to discover the old packaging hidden in a box.
It was made by Twenty First Century Games from Italy - Code 14.1
They also made a smaller Mayan Temple and raised dais to go with it in Code 14.2
