The first BENTLEY competed in the first 24 hours of Le Mans in 1923. The HELLER model proposed is a 4.5 Litres car with a compressor, the one which the pilot Sir Henry BIRKIN had built against the advice of W.O. BENTLEY for the 24 hours of Le Mans in 1930. Two models of this legendary car are still in existence at present, one of them in England and the other in the United States.
