1934 Duesenberg Model J LaGrande 'Sweep Panel' Dual-Cowl Phaeton
- Engine
- Supercharged straight-eight (engine no. J-537), rebuilt with Carillo connecting rods

The final example of the LaGrande 'Sweep Panel' Dual-Cowl Phaeton, chassis J-537 carries body number 1015 — last of approximately fifteen produced under the LaGrande label by Union City Body Company to a design refined by Gordon Buehrig. Completed in 1934 with skirted fenders and 17-inch wheels, it served as a New York factory demonstrator before entering private hands. After a 1958 fire caused limited cosmetic damage, the car passed through several distinguished enthusiast owners, culminating in a thorough restoration by Steve Babinsky that preserved all original sheet metal and earned multiple perfect CCCA scores, Pebble Beach First in Class, and other major concours honours.
