This short-wheelbase Model J is said to be one of approximately 45 built as a convertible sedan by the Walter M. Murphy Company. It was a popular choice for a Duesenberg body, and it’s easy to see why.

Power is from a 6.9-liter inline-eight that was fitted with a supercharger in the 1960s. The supercharger was an assembled unit, made up of original and reproduction parts. This is not a factory-supercharged car. Had it been, the factory would’ve claimed an output of 320 horsepower.

The history of this chassis is known back to its second owner, and it was acquired by the consignor back in 1990. Stashed away for decades, it would be a welcome sight at most shows. You can read more about it here and see more from this sale here.
