To Turbocharge Or Supercharge – Halford Special / Aston Martin #1916

In 1922 Bamford & Martin built 2 cars to compete in the French Grand Prix, the spare engine for this project was fitted to Razor Blade in 1923.

Bamford & Martin also built a number of vehicles for customers to race and the Halford Special carrying the chassis number #1916 and the registration number OR 1 was one of these. In 1923 W G Barlow is known to have competed with #1916 at the Aston Clinton Hill Climb, from which Bamford & Martin adopted the “Aston” and merged it with “Martin” to arrive at the ‘Aston Martin’ Marque name, and at Brooklands where he finished 4th in the JCC Spring meeting.

Captain G E T Eyston, later of Thunderbolt Land Speed Record Fame, drove #1916 in a Voiturette, (up to 1.5 litre / 91.5cui) race at Boulogne where he crashed. Major Frank Halford, who along with Eyston had competed with Razor Blade bought the wreck and replaced the 55hp four cylinder motor with a new 1.5 litre / 91.5 / cui twin plug, twin overhead cam, 12 valve, six cylinder motor of his own design. The Major fitted the motor with a turbocharger, probably the first to fit such a device to a racing car, but it proved unreliable in testing and so he reverted to using Roots type super charger driven off the crankshaft to produce 95 hp.

Fitted with a new two seater body #1916 the Major raced the car in 1925 only to find the radiator was too small. After it was replaced with a larger one, a second 120 hp motor fitted with a Berk supercharger was also used in the car which was renamed Halford Special. In 1926 the Major drove his Halford Special to 3 victories at Brooklands on the long and short tracks and “podiumed” on at least half a dozen further occasions.

Captain Eyston bought the Halford Special in 1927 and won another race at Brooklands before finishing 4th in the French Grand Prix run at Monthléry. During the 1930’s Viscount Ridley dismantled the Halford Special fitting one of the motors to his Bugatti Type 35 and the other into a speed boat which sank to the bottom of a lake, where it remained for two years.

James Cheyne, seen at the wheel of the Halford Special at Prescott, collected all the pieces and rebuilt the Halford Special in the 1970’s, since when it survived an accident at Silverstone in 2008.

Turbocharging eventually started making an impact on racing, first in the Cummins Diesel Special at Indy, in 1952 and ’53.

Poetry and Motion – Aston Martin Razor Blade

During the course of the coming month “Gettin’ a li’l psycho on tyres” will be celebrating the centenary of Aston Martin with posts featuring the marque on Saturdays, Sundays and Mondays and on Thursdays I’ll be celebrating the 60th Anniversary of the Corvette, Friday’s will be devoted to Ferrari’s and Tuesdays to Automobilia.

Lionel Martin and Robert Bamford founded Bamford & Martin in 1913 to sell Singer cars. The first car built by Bamford and Martin was given the marque name Aston Martin in 1915, but because of the Great War of 1914 – 1918 it did not go into production. The Aston name was adopted from the Aston Hill near Aston Compton where Robert Bamford and Lionel Martin were regular successful competitors.

During a period of post war financial turmoil and several bankruptcies up until 1926 Bamford & Martin built 55 cars for sale along with ‘Razor Blade’ which was built for in an attempt to become the first car to record an average speed of 100mph over one hour in a light car at Brooklands, however AC Cars pipped Martin & Bamford to the post recording 101.39 mph (163.17 km/h).

The chassis was specially made, but many of the remaining parts were standard Aston Martin items. The 55 hp 1.5 litre / 91 cui four cylinder motor, based on half a 1921 Ballot 3 litre / 183 cui 8 cylinder motor, was a spare Aston Martin had built for their 1922 French Grand Prix car.

The body work, built by the De Havilland Aircraft Company, is just 18 1/2″ wide at it’s widest point making it one of the, if not the, narrowest racing cars ever built. Originally an aerodynamic bubble was fitted on top of the cockpit and the car was temporarily known as “The Oyster”, but Lionel Martin could not find drivers diminutive enough to fit inside. SCH Davis managed to lap Brooklands consistently between 103 mph and 104 mph, faster than the one hour record set by AC Cars, but had to give up their record attempt because the front offside tyres repeatedly came off.

Major F.B. Halford was the first driver to race Razor Blade, crossing the line first in a handicap race, 5th on handicap, during the B.A.R.C. August Meeting at Brooklands and the following month the following poem appeared in the The Light Car and Cyclecar magazine :-

Major F. B. Halford
(The intrepid driver of the “razor blade” Aston-Martin racer)
With razor blades we’re all acquainted;
Some are good, others painted.
Halford Smiles; he’s found a winner;
Diet follows – make him thinner.

Later in 1923 the Major set a standing kilometer class record of 66.54 mph, while Herbert Kensington-Moir drove Razor Blade to a standing mile class record of 74.12 mph.

Razor Blade is seen in these photographs at Prescott Hill Climb with Colin Shaw at the wheel, above Razor Blade is seen next to the Halford Special built by Major F. B. Halford on an Aston Martin chassis which I’ll be looking at in greater detail tomorrow.
