Hispano-Suiza H6B chassis 10734, bodied in cabriolet form around 1932 by Fernandez or the nascent Fernandez et Darrin coachbuilder, combines Marc Birkigt's celebrated aircraft-derived six-cylinder engine with elegant low-slung French coachwork. Originally delivered in June 1923, the chassis was rebuilt at the factory circa 1929 before receiving its distinctive body. After decades of interrupted restoration passing through several notable owners, a comprehensive ground-up restoration culminated in a First in Class award at the 2024 Pebble Beach Concours d'Elegance.

Maintenance & restoration

  1. 1929Restoration
    Hispano-Suiza factory

    The chassis was returned to the Hispano-Suiza factory for a full rebuild, believed to have been prompted by accident damage; mechanical components were reportedly brought up to the then-current factory specification, including an updated engine block.

    Referenced in Emile Polo's La Hispano-Suiza; the original carburetor, distributor caps, and valve covers were retained despite the block update.

  2. 1932Bodywork
    Fernandez / Fernandez et Darrin

    A new cabriolet body was fitted by Fernandez or its successor Fernandez et Darrin, featuring a sweeping cowl, folding top with a disappearing-top well, nickel-plated brass beltline trim, and provision for dual side-mounted spare wheels.

    Exact attribution between the two firm identities is uncertain owing to a period of management transition when Howard Darrin joined.

  3. 2002
    Restoration

    A comprehensive ground-up restoration was begun under Otis Chandler's ownership but was not finished before the car changed hands.

    Work continued even as Chandler's health declined; the project was passed on unfinished.

  4. 2015
    Restoration

    A definitive full restoration was commissioned by Sam and Emily Mann, bringing the car to completion; the body was finished in black over light-gray leather, all trim was nickel-plated to original specification, Marchal headlights were fitted, and period details such as the disappearing top well and dual side-spare mounts were faithfully recreated based on surviving sheet metal and photographs.

    Chassis identity as 10734 was verified through collaboration with historian Hans Veenenbos and collector Al McEwan; the original serial number plate was absent and research was required to confirm the car's provenance.

  5. Restoration

    Partial restoration carried out during Dutch ownership, including coachwork rebuilding executed in Italy; sections of bodywork were re-skinned and re-framed where required, and the original fenders were restored. Work was left incomplete.

    Undertaken by or on behalf of the Bruijn and Paalman partnership between 1989 and 2002.
