This car took part in the Lancashire Automobile Club's Manchester to Blackpool Veteran and Vintage Car run in June 1986 starting from the Exchange Station car park in Manchester.
It's shown in the programme of the event as a 1926 Sunbeam 3-litre Super Sports and has a 2,920cc 6-cylinder inline twin overhead camshaft engine. A note about the car in the programme says:
1926 Sunbeam 3-litre Super Sports
Reg: ER 5678 6 cylinder 20.9 hp 2920 cc
(Kent S Robinson, Basingstoke, Hants)
This car was designed specifically for the Le Mans 24-Hour Race, where on the only occasion it competed it finished second driven by Chassagne and S C H Davis, despite a fractured chassis. It still makes an annual pilgrimage to Le Mans in June, its considerable performance making it an ideal touring car even today. In 1984 it successfully completed a tour of Spain, and only a fortnight ago returned from a nine-day European trip taking in France, Belgium, Luxembourg, Germany and Switzerland.
If this is that car then it should rightly be described as a 1925 car as the second placed car in the 1925 Le Mans 24-Hour Race was indeed the Sunbeam of Jean Chassagne and S C H Davis. The car was only offered for sale between 1926 and 1930 which is perhaps the reason for calling it a 1926 car.
