I saw this car in the paddock at the SeeRed meeting at Donington Park in June 2008 in a display of vehicles by H&H Classic Car Auctions and recognised it as one I'd seen racing in the late 1950s.
The programme of the event included a notice of a forthcoming auction at Buxton which was to include this car and contained this brief description of its history:
'1955/1957 Lister Sports Racer
This Lister began life with a Riley engine and was entered for the 1955
Bol D'Or 24-hours Grand Prix de Paris. It was converted to Bristol
power the following year and raced at national and international level
before crashing heavily at Snetterton in July 1957. Thereafter, the car
was rebuilt by the Works with new 'flatiron' bodywork. The Lister
has been in the current ownership since August 1969 but is offered
for sale as a restoration project (Bristol engine and gearbox included).
Estimate: £50,000 - £70,000.'
