Duesenberg Model J chassis 2319 was originally delivered with a formal seven‑passenger Willoughby limousine body, reflecting the traditional, chauffeur‑driven style favored by many early Model J buyers. Willoughby was well known for its refined craftsmanship and dignified designs, making such bodies particularly popular among clients seeking understated luxury.

In the 1970s, the car underwent a significant transformation. The original limousine coachwork was removed and replaced with a newly constructed body, designed as a replica Torpedo Phaeton. This change dramatically altered the car’s character, converting it from a formal closed car into a far more sporting and open configuration, in keeping with evolving collector tastes of the period.

At some point during this process, the original engine was also replaced. Chassis 2319 is now fitted with engine J‑396, a substitution not uncommon among Duesenbergs during the mid‑20th century, when mechanical components were often interchanged to keep cars operational.
