• One of 1,234 Bentley 4¼-litre cars produced from 1936–1939

• One of only twenty 4¼-litre chassis bodied by Mann Egerton

The Bentley cars produced in tandem with Rolls-Royces of the 1930s in Derbyshire have been overlooked by collectors until recently, due in part because they lacked the bulk and presence of the large-horsepower Rolls-Royce Phantom models and because so many Derby Bentley cars remained in daily service for decades.

As was the custom in the mid-1930s, a new Bentley buyer would have selected one of the bespoke coachbuilders to design and build his car’s body. While the car was being bodied, it was frequently inspected by Bentley representatives, who then gave it their final test before delivery. This car’s closed four-door saloon body was designed and built by Mann Egerton, established in 1901. During the pre-WWII years, they concentrated on Rolls-Royce chassis, though some of their designs were also fitted to Sunbeam, Daimler, and Bentley chassis. Noted for their soundness, durability, and finish, their distinctive razor-edged styling was admired and often copied. This is only one of twenty 4¼-litre chassis to be bodied by Mann Egerton.

Prior to being purchased by the current owner, B117KU was part the noted Gianaroli Collection for nearly 30 years. Finished in cream over black fenders, this Derby continues to present well with minor signs of ageing. The supple red leather interior contrasts nicely with the elegant and understated exterior. The 4¼-litre engine provides brisk acceleration, responsive handling, and a top speed of 96 mph, certainly quick enough for comfortable motorway cruising. It is deservedly one of the most popular tour cars in club events. As recent sales prices indicate, the Derby Bentley has come into great favour with collectors, not just British car enthusiasts. Few pre-war cars carry more graceful coachwork or offer more fun behind the wheel than the Derby. Exceptional examples with original engines and coachwork, such as B117KU, are always the quarry of astute collectors.
