The Vintage Sports-Car Club's annual Pomeroy Trophy meet is one of the most intriguing and entertaining events on the historic motor sport calendar.
Running to the arcane formula devised by Laurence Pomeroy – legendary technical editor of The Motor – to find the ideal roadable touring car, it consists of a series of tests (including fitting luggage into the car) and then is calculated against wheelbase and engine size and other factors to determine the winner.
Limited to cars of two litres or more (with smaller blown or turbocharged engines also admitted) the principal elements are the 'wiggle-woggle' slalom, acceleration and braking tests and then the 40 minute time trial with a target number of laps of the Silverstone circuit established for each competitor depending on their car's capacity and other factors.
Often taking place in gruesome winter weather, conditions for 2014 were unusually clement for the 70-plus entrants, but that is all that was different – the amazing spectacle of the competing machinery was as varied as ever.
Cars battling for the prize on 22 February ranged from Simon Diffey's flying Jaguar E-type to a Vauxhall Nova and a Ford Mondeo Estate.
Oldest car in the field was David Biggins' 1923 Crossley Sports, while the youngest was John Collins' Skoda Octavia. Michael Steele had the biggest engine, with his 7-litre Ford Galaxie earning him an unsurmountable 32 laps to complete, though that was still one fewer than Geraint Owen managed to do in his BMW M3.
But, despite the bewildering array of contenders, as has been the case in recent years, the pre-war Frazer Nashes dominated.
Fred Wakeman's 1928 Super Sports took overall victory and the Pomeroy Trophy (despite being docked points for an inadequate hood), while FN rival Charles Gillett, driving Patrick Blakeney-Edwards Owlet saloon, took the Densham Trophy for the next-best-placed pre-war car.
Third place went to Blakeney-Edwards himself in a TT Rep and the Frazer Nash clean sweep was completed by Martin Hunt in his Targa Florio.
Because there were no Edwardian entrants, the Pomeroy Edwardian Trophy was awarded to the best two-wheel-braked Vintage car, in this case Biggins' Crossley.
On a bright sunny Silverstone day, competitors await start of the tests.
Rudolf Ernst's 1925 Lorraine-Dietrich open tourer was one of the rarer cars at the event.
Adrian Goding was highest-placed post-war car, finishing 5th in his 1963 Ford Cortina.
Not the ideal track car – David Wylie's 1954 Armstrong Siddeley Sapphire saloon.
Bit of a performance mismatch: Chris Heyer's 1962 Alvis TD21 and Maxwell Whitehouse's 2001 Porsche 911.
Nick Leston's 1973 Porsche 911 dices with Charles Gillett's Frazer Nash in the first 40-minute high-speed trial. Leston finished 6th; Gillett 2nd.
Peter Batty's 1928 Ford Phaeton 35A tourer.
The first high-speed trial developed into a close "race" between the 1972 BMW 2002 of Richard Tyzack and the 1965 MGB GT of Oliver Eaton.
