This "Ultima Superleicht" was given to Eugene "Gene" Rito by Steyr-Daimler-Puch in appreciation for all the hard work Gene and his team at LifeCycle had done on designing and developing the Austro-Daimler brand in the U.S. This very bike was used in the 1976 A-D catalog. Except for the water bottle, it's 100% original.
