My book on Specialist British Sports/Racing cars says on this car: "Private owners were racing the HRGs with success in Club events throughout the 1950s and the last of the original square-rigged cars did not leve the HRG works until 1956. Although with the passing of the years HRG had turned more and more to other engineering work, the company had been carrying out development work on the Singer engine and produced a twin overhead camshaft cylinder head. David Bkaleky raced one of the ex-Le Mans cars fitted with one of these engines and he installed in his Emperor-HRG. The Emperor featured a tubular chassis, VW front suspension, deDion rear end and full-width aerodyanmic bodywork with prominent headrest. Blakely had driven this car into 2nd place in the 1500 cc race at the Boxing Day Brands Hatch meeting in 1954, it was a car of some promise and was being prepared for afull 1955 season at the time Blakely was murdered.
Unfortunately no reason is given for the Emperor name
