Chassis 9115609121 is the eighth of ten Porsche 911 RSR 3.0s built for the 1975 season, delivered new to the factory-supported Tebernum Racing team in Germany. It contested six rounds of the 1975 World Sportscar Championship and the European GT Championship, contributing to Hartwig Bertrams' European GT title that year. After sale to the United States, the car was fully restored by Ron Armour circa 1982, later passed through several noted Porsche collectors, and has since campaigned successfully in historic racing, winning its class at the 2016 and 2018 Le Mans Classic.
