Alfa Romeo 6C 2500 Super Sport chassis 915657, bodied by Carrozzeria Touring in its second-series Superleggera configuration, was completed in January 1949 and delivered to its first owner in Rome. One of approximately 120 second-series examples, it passed through American and European collections before entering rough condition. A multi-year restoration was completed under the supervision of H.D. Dambacher, with engine work by Aldo Zanone and final assembly by Carrozzeria Grillo. The car has since been used in historic touring events, including the 2010 Mille Miglia Storica.

Maintenance & restoration

  1. Restoration
    H.D. Dambacher

    A multi-year restoration begun under Dr. Montemezzi's ownership, ultimately completed by Alfa Romeo marque specialist H.D. Dambacher. During the process, numerous body panels were found to retain original body number stampings, confirming component authenticity.

    Restoration is said to have spanned approximately five years in total. A letter from collector Siegfried Otto Hepp corroborates that the crankshaft stamping matches the original engine number.

    Engine assembly and bench testing carried out as part of the broader restoration programme.

  3. Maintenance
    Autoselleria Brescia

    Interior retrimmed as part of the restoration.
