1924 Bugatti Type 35 Grand Prix
- 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.
