1924 Bugatti Type 35 Grand Prix

4394racingFrance
Engine
Inline-eight with Brineton crankshaft and connecting rods, Solex 35DH side-draft carburettors, Scintilla magneto

Bugatti Type 35 chassis 4394 is among the earliest examples of this celebrated Grand Prix model, completed in late 1924 and delivered to Lord Rocksavage (later Lord Cholmondeley) at Cannes in January 1925. It was campaigned at Brooklands in 1927 by Dorothy Campbell. After surfacing in a Kent scrapyard in the late 1980s it was restored, and questions have since arisen regarding the originality of the chassis, though the front axle, shock absorbers, radiator, and portions of bodywork are confirmed genuine. The engine was assembled by Laurent Rondoni with period-correct components.

Maintenance & restoration

  1. Restoration
    Keith Butti

    A restoration was carried out after the car was discovered in a Kent scrapyard, prior to its sale in 1990. The extent of work is not fully detailed, but the chassis is now believed to be a replacement unit.

    Restoration took place in the late 1980s; subsequent expert analysis by Pierre-Yves Laugier and David Sewell has assessed which components are original.

  2. Engine rebuild
    Laurent Rondoni

    The engine was assembled specifically for this car by Laurent Rondoni, incorporating a Brineton crankshaft and connecting rods, period-correct Solex 35DH side-draft carburettors, and a Scintilla magneto paired with gearbox number 29.

  3. Service
    Ventoux Moteurs

    Ongoing careful maintenance carried out by a leading French Bugatti specialist.

    Work performed during the current owner's tenure; described as careful upkeep rather than any major restoration.
