54 - When Ron Flockhart crashed Bira's 2504 while it was being tested by BRM, the damaged chassis 2504 was replaced by chassis 2509 and returned to Bira. The BRM modifications were stripped from 2509 and then transferred to 2504. Chassis 2504, now campaigning as '2509,' was repaired and used by the team until it the BRM P25 cars were ready.

55 - Horace Gould, Bristol, UK
As 2509, it was rebodied prior to the 1957 season. In 1958, the chassis - apparently as 2504 - was rebodied with 'Piccolo' bodywork. It was later returned to Italy and then sold to a client in New Zealand.

56 - returned to factory for rebuild  
- A new chassis was built using the old number, 2504 - although it was actually chassis 2509, and then returned to Halford  
- 58 2504/2509 was rebodied in 'Piccolo' bodywork and initially confused with chassis 2532, 2533, and 2534 as a fourth 'Piccolo' car. Several contemporary reports and others since then, recorded '2504' as the chassis Fangio used in his last race, in great part due to the new bodywork given '2504' during the re-build.
