1929 Bentley 4½-Litre Short Chassis

NX3463roadUnited Kingdom
Engine
4.5L inline-four
Colour
Blue over blue

Chassis NX3463 is one of only ten short-wheelbase 4½-Litre Bentleys constructed between 1927 and 1931, built to special order for repeat customer John Ward Cox and bodied as a four-passenger sports tourer by Vanden Plas. Among the rarest of W.O.-era Bentleys, it retains its original short chassis, numbers-matching engine and axles, and original body. After passing through a succession of noted owners — including the Brooklands racer Edwin Pacey — the car was thoroughly restored in the early 2010s by specialist Graham Moss, returning it to its distinctive original blue-over-blue livery.

Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
