The 1954 Series I, Pininfarina-bodied 500 Mondial s/n 0424MD was sold to Francois Picard in May, 1954. He soon sold it to fellow frenchman M. Dupont who raced it the rest of that year, and in mid-1955 traded it back to the Factory in exchange for one of the new Series II, Scaglietti-bodied 500 Mondials. The new Mondial, which would have been 0564MD in its sequence of manufacture, was given the first car's serial number, 0424MD, so that Mr. Dupont would not have to pay the outrageous French duty on a new race car. This was the exact same re-numbering scheme that occurred with our car, except done of behalf of Francois Picard.
So the Series II Mondial that would have been 0564MD has always worn 0424MD; its chassis and motor were both stamped as such. The motor now in the car is either the first or second replacement motor; I do not believe it was re-stamped, but is rather a Factory replacement motor not from another car (Dad will have to refer to his internal motor number spreadsheet for this). I believe the motor blew once for Picard in its maiden race at the 12 Hours of Hyeres, and then again for Dupont at least once, perhaps twice. Dupont took the car back to the Factory in August 1955, when the car was only 3 months old, for a motor problem. The story was that he was so disgusted w/ the problem, that he left the car there, never picked it up and never paid for the repair. The Factory painted it red and kept it on display at their museum until they sold it in the mid-1970s. My father can correct me if I got any of this wrong - doing it from memory here.
Terry, when you say "0424" I assume you mean the Series II car, and not the original 0424. The original Series I Pininfarina car is a "lost" car.
