Full story of the NZ carreer of #2504 can be found in Vercoe's book:
"Maserati 2504 started off as an A6GCM chassis powered by a 250F motor and delivered to White Mouse Stable for the Thai PRince Birabonge (...) to drive. (...). Shortly after his 'real' 250F chassis -2504- was delivered (...). The A6GCM was renumbered and sold to South America (...) and Bira's full-blown 250F adopted the 2504 chassis plate. (...). Bira then loaned the car to the Owen Organisation for the British Grand Prix as their own 250F had not arrived in time. The young Scot Ron Flockhart was the driver, but he inverted the car in the race, wrecking it. As Bira had just concluded a deal to sell the car to Horace Gould, he was a bit perturbated about Flockhart's accident. To appease Bira and Gould, the Owen group arranged for their own chassis, which was awaiting completition, to replace the damaged 2504. The Owen car was C2509, so that became C2504 and vice versa."
This is just the first part of it!
