1928 Bentley 4½-Litre Drophead Sports Coupe

XL3114roadUnited Kingdom
Engine
4.5L inline-four with shaft-and-helical camshaft drive

Chassis XL3114 is a 1928 Bentley 4½-Litre Drophead Sports Coupe built with an aluminium body personally commissioned by Fred Salmons of the Newport Pagnell coachbuilding firm Salmons & Sons, who used the car as his own and whose nickname 'Mr. Fred' it carries to this day. Notably, it is the sole example to bear polished Tickford wings on its doors at Salmons' own specification. After wartime and a period in the United States, the car was restored at the original Salmons & Sons works in the early 1980s. It retains its numbers-matching engine, axles, and steering column, and was invited to the 2020 Concours of Elegance at Hampton Court Palace.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections.
