This 1930 Duesenberg J 306 was built and cloaked in Willoughby seven passenger limousine coachwork. It was sold to Judge Rowe of Pittsburgh, Pennsylvania. Initially, the car was sold with engine J-383. Later the factory replaced that engine with J-306.
Willoughby built about 40 closed bodies for Duesenberg. About half were limousines. Every body had slightly different interior upholstery, door hardware, vanities and lighting. The intercom was produced by the Dictograph Company. It allowed a passenger to instruct the chauffer while keeping the division window sealed. The car has two jump seats, a special trunk rack and dual taillights. The tinted glass sun visor was specifically designed for the Willoughby Coachwork.
The car rides on a 153' wheelbase and comfortably carried five passengers. The engine produces 265 horsepower mated to Warner Gear three-speed transmission. Together they allow the car to exceed any legal speed limit by a wide margin.
