Chassis Num: CB/5/52
 
This is a 1952 Cooper Type 20 - Cooper Bristol MK1 with chassis number CB 5 52 and engine number 100/B2 4265. Its first owner was the Frazer-Hartwell Syndicate. It was raced during the 1952 season at Boreham, Turnberry, Cadours (France), Goodwood, and Charterhall.

In 1953 it was shipped to Argentina for the first Argentine Grand Prix with driver John Barber (8th place) and the ninth Buenos Grand Prix with driver Teddy Schwelm (12th place). Also Goodwood and Ibstock in the UK with drivers Jeff Sparrowe and George Hartwell.

In 1955 it was shipped to New Zealand by Jack Brabham and later entered in the 1957 New Zealand Grand Prix with driver Gavin Quirk (DNS). While in New Zealand it was raced extensively in hill climb and various other races.

In 1996 it returned to the UK and currently owned, maintained and raced by Brian Horwood.

This car is powered by a six-cylinder engine capable of producing 160 horsepower. It has a Reistor gearbox and transverse leaf spring suspension.
The Cooper T20 was produced beginning in 1952 and was powered by a L6 Bristol engine. The Bristol engine had been chosen because it was viewed as the best available 2-liter unit at the time. The manufacturer, Bristol Aeroplane Company based the six-cylinder engine's design on the pre-war BMW 328. The engine displaced 1971cc with hover-head valves actuated by cross-pushrods. In standard guise it produced nearly 130 horsepower, which was about 40 horsepower less than the competition.

The engine was lacking in power in comparison to its competition. Cooper chose to continue with the engine due to its availablity, reliability, and parts were in abundance. To compensate for its lack of power, Cooper devised an uncomplicated and lightweight chassis. The resulting car was the Cooper T20, also known as the Cooper-Bristol Mark I (MKI). A prototpye was debuted to the public at Hollyfield Road in early 1952.

The car was given a four-speed manual gearbox and a traditional Cooper suspension. The suspension included tranverse leaves and tubular wishbones. The chassis had been inspired by the Mark V 500 and featured a box-section chassis with holes drilled into the frame to reduce the overall weight. The steering was by rack-and-pinon with a 1.75 turns lock-to-lock. Located on all four corners were Cooper magnesium cast-type that measured 10-inches in diamater.

The prototype car was sold to Archie Bryde. Bob Chase purchase a T20 and it was raced by Mike Hawthorn who had much success with the car. At the Belgian Grand Prix, it was driven to a spectacular fourth place finiish. Late, a third place finish in the British Grand prix was achieved. A fourth at the Dutch Grand Prix earned him a fourth place finish in the World Championship. Hawthorn drove the car to a victory at the Lavant Cup where he was chased by two other Cooper-Bristols. Another victory was scored at the Formule Libre Chichester Cup.

Mike Hawthorn's career would continue with much success. The T20 had paved the way for this aspiring driver. The Cooper-Bristol T20 often outclassed the more powerful cars, though they had trouble beating the Ferrari's. It was Cooper's first Formula 2 car and was replaced in 1953 by the T23, also known as the Cooper Bristol MKII. The T23 had many improvements, such as a lighter tubular frame and larger brakes. The drum brakes of the MKI had been one of the vehicles achilles heal. The MKII's were given 11-inch Alfin light-alloy drums. The body was slightly redesigned, making it smoother and more aerodynamic. Powered by Bristol engines, the car failed to score any championship points during hte 1953 season. At the conclusion of the 1953 season, the cars were raced in Formula Libre classes, by such memorable names as Australia's Jack Brabham.

During the very early 1950s, Cooper had built a reputation by dominating the Formula 3 class. This had been a profitable venture and the company had wanted to diversify by moving into the Formula 2 class. Their customers had been asking for a Formula 2 car in which they could continue to climb the racing class ladder. Thus, the creation of the Formula 2 Cooper T20 MKI's. The car had proved capable, but more was required to become a serious contender. Hawthorn joined with Maranello in 1953, competing in F1 competition under the Ferrari banner. His career would continue for several years, mostly at the wheel for Ferrari's and Maserati's.

Coopers next iteration of the T20 was the Mark II, T23. All, but one, of the cars were powered by Bristol engines, still with the engine being placed in the front. One example was given a BRG Alta engine and owned by Peter Whitehead and driven by Moss.

One of the factory drivers was Britshman, John Barber. He traveled to Argentina at the start of the 1953 F1 season to compete with his Cooper T23. He managed an eighth place finish, seven laps down from the victor. Cruz Schwelm entered an MKI, but it retired prematurely due to mechanical problems.

Alan Brown and Cruz Schwelm retired in the Buenos Aires City Libre GP, and Barber managed an 11th place finish in the Mark II.

At the close of the season, Gerard and Moss had managed some victories in minor events. The Cooper MKI and MKII models continue to race, with some being converted to sports racing cars. Some of the cars had success in the Formula Libre class and in Formula 1, though with larger engines and improvements throughout the vehicle.

The 1953 World Championship season had run under Formula 2 regulations. At the close of the season, the regulations changed to 2.5-liters in natural aspirated. Cooper decided to focus on Formula 3, unveiling the newest contender, the Mark VIII 500 in October. The 'curved-tube' concept was unveiled to the public where its streamlined body was hailed as the sleekest Cooper to-date.
Formula 2

Formula 2, commonly abbreviated as F2, was introduced in 1947 and would remain in existence until 1985 when it was replaced by Formula 3000. F2 enabled drivers who could not get a seat in Formula 1 to compete internationally. In terms of open-wheeled auto racing, Formula One is the pinnacle of the sport and the dream of the aspiring driver. The high speeds and costs associated with F1 are great; F2 has provided a means of allowing a driver to mature and gain experience before venturing on to the next step. In pre-war time, the F2 sport was often known as 'voiturette' which means 'small car.' Voiturette racing cars were permitted 1.5-liter supercharged engines while the Grand Prix cars were allowed 3.0-liter supercharged or 4.5-liter size in naturally aspirated form.

After the war, Formula A and B were introduced, later known as 1 and 2 respectively. Formula A allowed 4.5-liter supercharged cars. Formula B/2 had smaller, less powerful cars than those used in Formula A/1. The rules stated that the engines in F2 were to at most 2-liters in size; 750cc if a supercharge was used. This allowed smaller marques to build racers without having to compete with the most dominate and well-established manufacturers.

In 1952-53 Formula 2 counted for the Drivers World Championship, since Formula One had become so expensive that were so few entrants. Non-championship F1 races were still held during this time. In 1954 the rules of F1 changed allowing 2.5-liter engines which drew some of the popularity away from F2. F2 rules were changed in 1957 limiting engine sizes to 1.5-liters. The dominant engine of choice was the Coventry-Climax FPF four-cylinder.

In 1967 FIA introduced the European Championship for Drivers for F2 category. This had many Formula One drivers switching to F2. The grading system in F2 allowed this; any driver with an 'A' grade was not permitted to score championship points. The 'A' grade was earned through various means such proving themselves in Grand Prix or World Sports Car events. This allowed the less experienced drivers the opportunity to works towards a championship victory and to mature their careers. It allowed the seasoned drivers an opportunity to continue their driving passion and improve their skills during the off-season of Grand Prix racing.

In 1972 the engine size was increased to 2-liter production based engines. In 1976 the rules were modified to allow engines that had been created if the intent were purely for racing. Near the close of the 1970's and into the early 1980's, the costs to compete had sky-rocketed. Works racers had become the dominate force of contention and privateers were unable to keep pace. Interest in the sport dwindled as drivers left for other series. By 1984, the Formula Two series was replaced with Formula 3000.
