“Bertram had handled the car beautifully, not very high on the banking and never giving a real impression of his actual speed. His two laps had been covered at 142.03 mph and 142.60 mph respectively, his fastest time being 69.85 seconds. Cobb’s record was 70.68 seconds or 140.93 mph.”
In the event, Bertram’s overall lap record stood for barely a month. Cobb raised the benchmark to 143.44mph in October but the Barnato-Hassan held on to the Class B record for engines up to 8000cc: the Napier-Railton’s 23,890cc motor putting it squarely into Class A.
Hassan continued to work on the car during Brooklands’ sunset years and Bertram lapped at more than 143mph in 1938 but it wasn’t recognised, as it took place during a race. When the circuit closed in 1939, its earlier Class B record still stood unbeaten.
In the last 84 years, the car has gone on to five different owners and has raced on at classic events, including at Goodwood and Silverstone.
Hassan went on to work with Cobb on his land speed record-breaking Railton Special. He joined Jaguar and was involved in five Le Mans wins of the 1950s; he also developed the Coventry Climax engine into a world championship winner with Cooper.
The Barnato-Hassan Bentley is being sold by Vintage Bentley and will be on display at Salon Privé at Royal Hospital Chelsea in London on 21-23 April.
