A 1929 Rolls-Royce 40/50hp Phantom II Weymann Sports Saloon is one of the highlights of the Collectors’ Motor Cars and Automobilia sale at Bonhams Oxford on March 5.

The car is estimated to sell for £180,000 – 200,000.

The Phantom II was reputedly the last model that Henry Royce designed himself.

Immediately after the end of the Great War the recession in the motor trade prompted Rolls-Royce to introduce a smaller, cheaper 20hp car to be built alongside the existing 40/50hp Silver Ghost.

In 1925, the New Phantom (known as Phantom I) was introduced, taking Henry Royce’s designs from the old Silver Ghost as well as using the developments and modern features pioneered on the smaller 20hp car.

Unlike its predecessor, which inherited its underpinnings from the 40/50hp model, the Silver Ghost, the Phantom II employed an entirely new chassis inspired by the smaller 20hp Rolls-Royce as well as a new engine.

The Phantom II chassis provided a platform for some of the truly outstanding designs of its day, and was favoured by prominent coachbuilders. The example offered by Bonhams carries Weymann-type sports saloon coachwork by H J Mulliner.
