Are you sure it was a 3rd Series. The car was protested on the 1954 Monte Carlo Rally after finishing with the lowest penalties. It was claimed the 2.5 litre engine did not match the chassis number, which, and I could well be wrong, was from a second series. Although 500 third series cars were homologated the actual Aurelia/Chiron car was an earlier second series 'works' car fitted with the later engine and not from that batch The protest went all the way to the FIA in Paris who eventually relented and declared Chiron the winner, three months after the Rally.
