Brian JB Naylor and Fred Wilkinson.

This car was constructed by racing mechanic Fred Wilkinson for his long time friend Stockport car dealer Brian (JB) Naylor. Wilkinson built 3 cars for Naylor, a JBW Maserati sportscar powered by a Maserati 200 S engine (the car won 14 out of 20 races entered), JBW Ferrari sportscar and the 2½-litre JBW Formula One shown here that used a Maserati 250 S engine.

Wilkinson designed and built this first JBW F1 car in 1959, following the Cooper rear-engine format and adopting a four-cylinder Maserati 250S engine and a five speed transaxle. That year it was entered in only 3 British races. At Silverstone in the International Trophy (50 laps) it retired on lap 41 with a broken gearbox, at the British GP (75 laps) it retired on lap 18 with a broken transmission whilst lying in 11th position and following a crash during practice, it was a non-starter in the Oulton Park Gold Cup.

In 1960 Naylor undertook a more active season, competing in the International Trophy, at Monaco (failed to qualify), the British GP (qualified 18th from 24 starters and finished twelfth, some five laps down), the Silver City Trophy at Brands Hatch, the Italian GP, Snetterton, Oulton Park and the American GP at Riverside. Unfortunately, the car was blighted by retirements.

In 1961 this same car was entered in the Inter-Continental Formula races such as the Lombard Trophy, the International Trophy, the British Empire Trophy and the Guards' Trophy, but was hopelessly outclassed and failed to finish in any of the races.

In 1961, another Cooper-influenced JBW F1 car appeared, this time with a Maserati 150S engine and a five-speed Colotti gearbox. In the Silver City Trophy at Brands Hatch it retired with overheating after having been some ten seconds off the pace. It ran again in the Italian Grand Prix, this time with a Coventry Climax FPF engine, but after six laps it retired with a blown engine. In the Oulton Park Gold Cup it finished ninth and in its final race, the Lewis-Evans Trophy at Brands Hatch, it retired on the first lap.

It was after this last retirement that Naylor retired and returned to Stockport to concentrate on his car dealer business.
