1935 Aston Martin Ulster

B5/549/UracingUnited Kingdom
Engine
1.5L inline-four, dry-sump, 100 mph capable

Aston Martin Ulster chassis B5/549/U (registered CMC 614), built in 1934–35 as a Works racing car for E. R. Hall, has an unbroken documented history stretching back to its first competitive season. It contested the 1935 Mille Miglia, Le Mans, Targa Abruzzo, and RAC Tourist Trophy before passing through several private owners. Its longest custodian, Derrick Edwards — founder of Ecurie Bertelli — raced it worldwide for four decades, claiming an estimated 650 awards. Original components displaced during that period were subsequently refitted, making this one of the most intact surviving pre-war Aston Martins.

Maintenance & restoration

  1. 1935Repair
    Aston Martin Works

    Following the oil-leak retirement at the Mille Miglia, the car was returned to the Aston Martin factory for remedial work before its Le Mans entry.

  2. Modification

    A supercharger was fitted during H. H. Porter Hargreaves' ownership, necessitating a visible bulge in the bodywork — the sole external change to the car across its entire lifespan.

    This modification is the only alteration apparent in period and later photographs.

  3. Restoration
    Ecurie Bertelli

    Following Edwards' death, the new owner had all original parts that Edwards had carefully set aside during his racing years reinstalled on the car. Only one body panel had been replaced, and the original piece remains held by Ecurie Bertelli.

    The work was carried out under Fred Blakemore's ownership and aimed to return the car as close as possible to its original specification.
