As the first Bentley designed following the end of World War II, and the firm’s first model built at the Crewe plant, the Mark IV holds two distinctions. However, the significance of chassis B342NZ is greater still. From the final year of production, it gained the enlarged “Big Bore” 4½-litre (4.6) six-cylinder engine. While most of the 4,001 examples produced between 1946 and 1952 gained the factory’s Standard Steel Saloon body, this Drophead Foursome Coupé is the only car to have received coachwork by Mulliners of Birmingham.

The unique lines were the work of Stuart Peck, with the commission owed to Standard Motor Cars Managing Director, Sir John Black. Rising to the rank of Captain during World War I, he subsequently oversaw the construction of over 20,000 aircraft engines and 1,066 De Havilland Mosquito fighter-bombers to earn a knighthood in 1943. Sir John sold his Bentley to its next owner in Bournemouth before the car was exported to California, United States. Come 1973, the car was acquired in the state and ultimately stored for some 37 years by Dr Kurt Hammerstrom. Chassis B342NZ was then sold to an avid marque enthusiast ahead of an extensive restoration that lasted for five years and required over 12,000 hours of labour.

At this time, the original black colour scheme was changed in favour of the current three shades of grey. Also fitted was the red hide featuring grey piping and Art Deco-inspired door cards while the hand-wound clock mounted on the glovebox, above the concealed tool kit tray, was retained. Given the quality of the work carried out, the Mark IV was exhibited in the post-war Touring class at the 2014 Pebble Beach Concours d’Elegance. Further accolades include being named Best in Class and Most Elegant Open Car at Ironstone, Best in Class and Best of Show at the Niello Concours, and Best in Class at Hillsborough.

Purchased by the consigning owner, a collector of prestigious Rolls-Royces and Bentleys, in August 2018 and then imported to the United Kingdom, this car is accompanied by its hub spanner, spare wheel, and extensive history file that documents the ownership chain, original build details, and restoration.

An exquisite and unique version of an already-significant Bentley, chassis B342NZ boasts a fascinating back story to ultimately make for a wonderful addition to any collection.
