1929 Rolls-Royce Phantom II Hooper Boattail Speedster
- Engine
- 7.7L OHV inline-six, ~160 bhp
- Colour
- Black with scarlet

Rolls-Royce Phantom II chassis 23GN is a uniquely sporting open tourer bodied by Hooper & Company to exacting personal specifications for Sir Julien Cahn, a prominent cricket patron and businessman, in 1930. The coachwork features a tapered boattail rear deck, a hidden rear seat with its own soft-top, and no bumpers — a configuration unlike any other Phantom II. After wartime military donation and post-war sale, the car passed through several British owners before crossing to the United States, where it received a comprehensive restoration and won the Lucius Beebe Memorial Trophy at the 1997 Pebble Beach Concours d'Elegance.
