Brooklands 2x12 Hours '1907–39

8 ноября 1909 года Виктор Эмери в Брукланде, Англия, установил рекорд скорости 202.69 км/ч (125.946 миль/час). Это был первый заезд с использованием электронного хронометража.

Короткие круговые трассы Европы не давали автомобилю полностью раскрыть свой потенциал, и в 1910 году Benz 200HP, оснащенный новым, очень узким обтекаемым кузовом был отправлен в Америку, где Барни Олдфилд 17 марта 1910 года в Дайтона-Бич развил скорость 211,27 км/ч (131.275 миль/час), а 23 апреля Боб Берман на этом же автомобиле, получившим прозвище "Молния Бенц" установил новый рекорд скорости на дистанции один километр со стартом с хода — 227.51 км/ч (141.37 миль/час). Рекорды в Дайтоне не были засчитаны, так как AIACR (Association Internationale des Automobile Clubs Reconnus) установила новое и справедливое правило для рекордных попыток, которое предусматривало, что попытки должны быть сделаны в двух направлениях, чтобы исключить любую помощь от ветра. Однако американцы не признали это правило.

24 июня 1914 года в Брукланде, Англия, Лидстон Хорнстед на Benz 200HP предпринял первую попытку рекорда по правилам AIACR, и по результатам двух заездов его рекорд составил 199.71 км/ч (124.095 миль/час).

LM3 had its track debut in the first ever Double 12 Hour meeting at Brooklands with Augustus Bertelli and chief mechanic Jack Bezzant sharing driving duties finishing a creditable 5th. In 1930 the original body was changed by the factory, presumably because it was too light. Not much later the vehicle became the Works Team Aston Martin development and road test car, lent out to journalists to drive and report on. Before the car was sold to Peter Farquarsonin 1932, the Astin Martin was re-registered GX599 and 129R was added to the original chassis number.

1930 was a very good year for LM4 and Aston-Martin, ‘Bert’ Bertelli and Holder drover LM4 to 2nd in class and an incredible 4th overall at the 1930 Brooklands Double Twelve; this feat warranted a glowing article in the June edition of Motorsport a copy of which, Ecurie Bertelli holds in our extensive archives. Sammy‘ Davis drove this car to 7th and 1st in class at the Irish GP at Phoenix Park. 1930 was a very good year for LM4 and Aston-Martin, ‘Bert’ Bertelli and Holder drover LM4 to 2nd in class and an incredible 4th overall at the 1930 Brooklands Double Twelve; this feat warranted a glowing article in the June edition of Motorsport a copy of which, Ecurie Bertelli holds in our extensive archives.

According to a previous owner, this particular Riley racing car was an early 9 chassis, developed for competition at Brooklands by Thompson and Taylor at the factory's request, and featuring numerous changes from the company's standard automobiles, developed by Parry Thomas and Reid Railton. At its completion the frame was sent back to the Riley Works, stamped as 8046, and received a Riley Works racing engine, of the same specification used for the Irish Grand Prix cars of 1930 and 1931. It was reportedly the first of its kind produced to the lightweight, aluminum-bodied "Brooklands" specification. Following restoration, the car was enthusiastically driven, including appearances at the Le Mans Classic and Le Mans Legend events, and at the 2009 Monterey Historics.
