1931 Duesenberg Model J Derham Tourster, long-wheelbase five-passenger touring
- Colour
- Soft yellow

Chassis J-448 is the fourth of eight authentic Duesenberg Model J Toursters bodied by the Derham Body Company of Rosemont, Pennsylvania — a five-passenger touring design on the long 153.5-inch wheelbase, conceived by Gordon Buehrig as his personal favourite among all his Duesenberg work. Delivered new in September 1931 to a New York and Paris-based arts figure, the car passed through several notable American collectors over subsequent decades. A mechanical restoration was carried out by specialist Joe Kaufmann, and a later comprehensive restoration by RM Auto Restoration produced the current yellow and green livery. The car retains its original numbered crankshaft and has accumulated an extensive concours record, including Best of Show and Best in Class victories at multiple major events.
