Retained as a factory demonstrator following the Paris Auto Show; used by factory personnel Pierre Veyron and Adrien Paul for demonstration drives in Belgium and Geneva.

Delivered in Geneva; never formally imported the vehicle into Switzerland from France, and may still have held the car when it was registered in Paris in 1949.

Car was registered in Paris in 1949; identity of registrant unclear, possibly the same prior owner who never completed a formal import to Switzerland.

Paris-based garage proprietor who simultaneously held two other Type 57 Bugattis; sold the car roughly one year after registering it.

American artist and student residing in Paris who owned several Type 57s; transported the car to the United States upon returning home. A Paris-issued license plate found later was titled to him, corroborating the car's true chassis identity.

Listed as owners in the 1973 Bugatti Register; based in Scarsdale, New York.

Art dealer specialising in abstract expressionism and a major Bugatti collector, reportedly owning close to thirty examples; documented in the 1979 and 1988 American Bugatti Register.

Noted French-American painter and sculptor who acquired the car in 1988.

Prominent collector during whose tenure the mid-1990s concours restoration was completed at Ivan Dutton Ltd at a cost of approximately $450,000; drove the car regularly and attended the 1998 Pebble Beach Concours.

Held the car for approximately four years as part of a well-regarded private collection.

Prominent period enthusiast who also owned a Duesenberg and multiple Bugattis, including chassis 57664. Commissioned a full restoration with a rebuilt engine, new mahogany dashboard, and Jaeger instruments; during this work the engine and data plate were swapped with those of 57664.

Zurich-based owner who repatriated the car to Europe; discovered a Paris-titled license plate inside the vehicle that was later confirmed to belong to chassis 57584 under Hassrick's name.

The inaugural Tour d'Elegance was held that year, inviting concours entrants to drive publicly on surrounding roads; this car was judged the most elegant vehicle observed in motion during the tour.

Full restoration carried out under W. Hudson Mills's ownership: engine completely rebuilt, a new Honduras mahogany dashboard installed with Jaeger instrumentation. During this work, the engine and data plate from chassis 57664 were substituted into 57584.

The engine swap introduced decades of chassis misidentification.
