Duesenberg Model J chassis 2406 is a particularly fascinating and technically significant example, representing one of the rare factory-supercharged SJ variants, combined with elegant and sporting Murphy Disappearing Top Convertible Coupe coachwork.

The supercharged Duesenberg engine, still a 420‑cubic‑inch Lycoming straight eight with dual overhead camshafts and four valves per cylinder, produced an astounding 320 horsepower at approximately 4,000 rpm, making it one of the fastest production automobiles of its time, capable of speeds approaching 135 mph.

Between 1932 and 1935, Duesenberg produced only 36 such supercharged chassis, each sold at a base price of $11,750, with fully bodied examples often exceeding $20,000, a staggering sum during the Great Depression. Chassis 2406 is one of these rare and highly desirable cars.

Interestingly, the car displays a unique combination of design cues:

- Semi-circular hood cutouts on the opposite side, more commonly associated with standard Model Js

This unusual mix of features highlights the evolving and often bespoke nature of Duesenberg construction and later modification.

This design allowed the folding convertible top to be fully concealed beneath a flush rear deck, creating a smooth, uninterrupted silhouette. Combined with Murphy’s clean lines and restrained use of chrome, the result is a car that perfectly balances elegance and sportiness, often considered the definitive expression of the Model J.

Among early custodians was media magnate William Randolph Hearst, further enhancing the car’s prestigious provenance.

In 1939, the car was acquired by Norberto Angones y Quintana, First Secretary of the Cuban Embassy in Paris. Under his ownership, the Duesenberg embarked on an extraordinary journey, traveling across Cuba, France, and Spain, reflecting the international appeal of the marque.

In subsequent years, the car passed through several knowledgeable owners:

- Robert Gottlieb, noted automotive author and founding member of the Classic Car Club of America, who secured ACD Club certification.

In 2000, the car received a fresh finish in an elegant dark garnet red, enhancing its already dramatic presence.
