There is another version of the model J known as the Duesenberg JN (a name never used by the company either). All JNs were sold with Rollston coachwork and only ten were produced in 1935. In an attempt to give a more modern look to an ageing design, the JN was equipped with smaller -diameter wheels (versus ), skirted fenders, bullet-shaped taillights, and bodies set on the frame rails for a lower look. The battery box and tool box were redesigned slightly so that the doors could close over the frame. Supercharged JNs gained the logical SJN designation.
