From Wikipedia:
Vanwall was a motor racing team and racing car constructor that was active in Formula One during the 1950s. Founded by Tony Vandervell, the Vanwall name was derived by combining the name of the team owner with that of his Thinwall bearings produced at the Vandervell Products factory at Acton, London. Originally entering modified Ferraris in non-championship races, Vanwall constructed their first cars to race in the 1954 Formula One season. The team achieved their first race win in the 1957 British Grand Prix, with Stirling Moss and Tony Brooks sharing a VW 5, earning the team the distinction of constructing the first British-built car to win a World Championship race. Vanwall won the inaugural Constructors' Championship in Formula One in 1958, in the process allowing Moss and Brooks to finish second and third in the Drivers' Championship standings, winning three races each. Vandervell's failing health meant 1958 would be the last full season; the squad ran cars in a handful of races in the following years, but finished racing in 1961.
Tony Vandervell was one of the original backers of British Racing Motors. In the early 1950s he entered a series of modified Ferraris in Formula Libre races under the name "Thinwall Special".
The first actual Vanwalls were known as Vanwall Specials and were built for the new Formula 1 regulations in 1954 at Cox Green, Maidenhead. The chassis was designed by Owen Maddock and built by the Cooper Car Company. The 2.0 L engine was designed by Norton Motorcycles engineer Leo Kuzmicki, and was essentially four Manx single-cylinder 498 cc (30.4 cu in) (86.1 mm × 85.6 mm (3.39 in × 3.37 in)) engines with a common waterjacket, cylinder head (a copy of the Norton's) and valvetrain, with induction by four AMAL motorcycle carburetors. This combination was fitted to a Rolls-Royce "B"-engine crankcase, copied in aluminium. Designed for Formula Two, which was supplanted before it appeared, the car debuted in a Grande Epreuve in the 1954 British Grand Prix. Against 2½ litre Formula One competition, it was at a decided disadvantage. The Goodyear disc brakes (built by Vanwall) proved successful, but the front suspension and fuel and cooling systems were troublesome. Development continued with a switch to Bosch fuel injection (thanks to Vandervell's "persuading" Daimler-Benz, a major Bosch customer, to allow it), while retaining the AMAL throttle bodies; they were plagued with throttle linkage trouble, due to vibration from the big four-cylinder. Vanwall also increased the capacity of the engines, first to 2,237 cc (137 cu in) (91.0 mm × 86.0 mm (3.58 in × 3.39 in)) for Peter Collins at Monaco 1955, and then a full 2,489 cc (151.9 cu in) (96.0 mm × 86.0 mm (3.78 in × 3.39 in)). Vanwalls then ran for a season in F1 without much in the way of success. At the end of the 1955 season, it was plain that the engine was sound, but that the Ferrari-derived chassis needed improvement. It was suggested to Vandervell that he should hire the services of a young up-and-coming designer to improve their cars. The designer was Colin Chapman.
The new 1956 cars designed by Chapman (along with the aerodynamicist Frank Costin) were of space frame construction, the De Dion rear axle's unsprung weight reduced and front torsion bar added (none of these ideas were revolutionary, but Chapman was happy simply to be meticulous). Furthermore, a fifth gear and Porsche synchromesh were added to the transmission. The driving seat was placed above this and could not be reduced below 13 in (330 mm) above the road, making the height very problematic (the top of the driver's helmet was fully 50 in (1,270 mm) from the road surface, while the vertically mounted engine made a reduction impractical in any case), and the handling was suspect despite Chapman's best efforts.[2] The solution which today is obvious, mounting the engine behind the driver, would take two more years to be accepted. Costin made the most of it, and produced a car "much faster in a straight line than any of its rivals".
The new car showed early promise in 1956 by winning the non-championship F1 race at Silverstone against strong opposition. It set the lap record at Syracuse. Stirling Moss drove the car to victory in what was his only drive for Vanwall that year, as he was still contracted to drive for Maserati in F1. Talented drivers Harry Schell and Maurice Trintignant were the full-timers for the season. However, neither of them had much success although the car showed obvious potential.
With the car developing and becoming ever more competitive, Moss eventually decided to drive for the team in 1957. He was joined by two Englishmen, Tony Brooks and Stuart Lewis-Evans. As the 1957 season unfolded, the cars became faster and more reliable. Moss and Brooks duly shared Vanwall's first Grand Prix victory in Britain at Aintree, and Moss went on to win both the Italian and Pescara Grands Prix.
At the end of 1957, alcohol fuels were banned and replaced by a compulsory 130-octane aviation gasoline. This caused problems for Vanwall and BRM with their large bore engines that required methanol for engine cooling. As a result, the Vanwall's power dropped from 290 bhp (220 kW) at 7,500 rpm[5] (308 bhp with nitromethane) to 278 bhp (207 kW) on the test bed. During the race, where revs were reduced, only 255–262 bhp at 7,200–7,400 rpm was available. This put them at a disadvantage to the new Dino Ferrari V6 cars with a claimed 290 PS (286 bhp) at 8,300 rpm. The Vanwall's superior road holding (thanks to suspension changes, new steel wheels, and new nylon-cord Dunlop R5 racing tyres), streamlining, 5-speed gearbox, and disc brakes helped to offset this.
All three drivers stayed with the team in 1958, and Moss (wins in the Netherlands, Portugal and Morocco) and Brooks (wins in Belgium, Germany and Italy) each won three championship races that season. Vanwall became the first team to win the Constructors' Championship, held for the first time that season. However, Moss lost out to Mike Hawthorn in the Drivers' Championship by a single point to finish second, with Brooks ending the season in third. Their triumph at the end of the season was sadly marred when, during the final race of the year in Morocco, Lewis-Evans was fatally injured in an accident.
The 1958 season was the last one in which Vanwall entered every race. Vandervell's health was failing and he had been advised by his doctors to rest. The team continued half-heartedly. Brooks made one appearance in a lower and lighter Vanwall at 1959 British Grand Prix, proving less successful against the new mid-engined Coopers, and the team tried again with another car in the 1960 French Grand Prix. These efforts lacked the seriousness of the past however and they were unsuccessful.
The last racing Vanwall was an "unwieldy" rear-engined machine produced for the 1961 3.0 litre Intercontinental Formula. Although showing promise when campaigned by John Surtees in two races, development was stopped short when the formula did not find success in Europe. The engine was enlarged to 2,605 cc (159 cu in) (96.0 mm × 90.0 mm (3.78 in × 3.54 in)), rated at 290 bhp (220 kW) on 100 octane petrol.

) in its slots on the lower body half... It was clear that the "firewall" in front of it was too near to make room for driver's legs, as it was too low... so, i cut it away leaving two sides that I needed as a reference and supports to glue the new panels... I also glued the rear axle in its place...
