Yes, the McLaren M10B (ex David Prophet) has been owned and raced by Bruce Leeson for many years. Bruce is an Australian living here in California. One of his incarnations was as a motorsports photographer and magazine contributor in Australia during the heyday of F5000.
Bruce is quite fast and has raced the car in the US, NZ, and OZ. He actually won the Class-A (older chassis) honors at the Australian Grand Prix F1 support race (Tasman Cup Revival) a few years ago.
