I hope you're progressing, we still miss pictures of the hole beauty as complete bike
Just came across another old documentation of a Vario bike.
This picture shows the german Bike racer Regina Stiefel at an Bike event at lake Garda in 1996.
She has just changed her Sponsor, and was racing now for the American Eagle bike team, but as they haven't had something proper to replace her Vario DH bike, she has used Letraset letters to add the name of her sponsor to her bike.

It's hard to identify her fork, maybe this was a Rond DH dual crown fork?
