1929 Bentley 4½-Litre Short Chassis
- 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.
