In the 1949 BRDC/"Daily Express" International Trophy, Peter Walker took GP1 to within 1.2 seconds of Giuseppe Farina's Maserati in practice and finished fifth in the race, despite gearbox and steering problems, a leaking radiator, and the exhaust burning the driver's foot. Walker was fastest in practice for Ireland's Wakefield Trophy road race, but a snatching brake forced him down the escape road at the first corner. Here GP1's race ended when it was hit by an Alta that had already collided with Salvadori's Maserati 4CL.
