A 1948/1949 Alfa Romeo 6C 2500 Super Sport with coachwork by Touring in the lightweight Superleggera technique, factory-equipped with the Nardi conversion including a three-spoke steering wheel and floor shift. Assembled in December 1949 and finished in light green, this chassis passed through Italian and American ownership over several decades before undergoing two major restorations — the second a seven-year, $500,000 effort by Bonfanti Garage in Italy returning it to original specification with period-correct components.
