Shawe-Taylor started racing before the war, winning the Nuffield Trophy in 1939. After the war he raced an ERA, with which he tried to enter the 1950 British Grand Prix. The organisers deemed his car to be too old, but he managed to take part in the race anyway, by sharing the Maserati 4CL of Joe Fry. The following year, he practiced a Ferrari entered by Tony Vandervell at the 1951 French Grand Prix, but ultimately Reg Parnell drove the car during the race.
