This is a long-chassis 20/25hp carrying formal saloon-with-division coachwork by Windover.

The 20/25 was built between 1929 and 1936, with a total of 3827 being made. According to Bonhams, this particular car was first owned by Lord Ennisdale, Chairman of Harrier Fighter Planes during WW2.

In place of the usual “Spirit of Ecstasy” bonnet ornament, the Chairman fitted his own personal mascot, Pegasus, the winged horse of Greek mythology.

As with all models of the period, only the chassis and other mechanical parts were Rolls-Royce. The body was made and fitted by a coachbuilder selected by the owner, in this case Windover.


Windovers were originally saddlers and harness-makers dating back to the 17th century, until the onset of the Industrial Revolution, when they began to engage in carriage and coach building.

Windover-built carriages developed a loyal following and were in evidence throughout the British Empire, as well as the royal households of England and other European locales.

As the motoring age dawned, Windover was a natural choice to produce bodies for the top marques, including Rolls-Royce and Bentley.

The interior has been re-upholstered in leather throughout (the rear compartment’s upholstery was cloth originally). Accessory driving mirrors to the A-posts and indicators fitted discreetly beneath the bumpers are the only other deviations from original specification notified. In 1995 a new cylinder head was fitted.

Other noteworthy features include dummy pram irons, a wind-down interior glass partition and vanity cabinets for the rear seats (for last-minute make-up alterations!)

The same model (albeit with Barker Saloon coachwork) appeared in Indiana Jones and the Last Crusade, as enthused over by Alexei Sayle’s Sultan of Hatay (“…and I even like the colour!”) However, the Sultan refers to the car as a Phantom II, presumably because it sounded better!
