1929 Duesenberg Model J Dual-Cowl Phaeton by Murphy
Offered by RM Sotheby’s | Monterey, California | August 12-14, 2021
There are a lot of Duesenbergs coming out of the woodwork for Monterey this year. This is the third Wednesday in a row we’ve featured one. The dual-cowl phaeton is the best Model J body style, and this is a rare variant of the breed.
Murphy’s designer decided to cut the rear cowl (the folding windshield between the two rows of seats) down the middle, so either side could flip up independently, allowing passengers from either side to enter without having to heave the entire cowl upward. It was dubbed the “butterfly” dual cowl, and only three were built.
Power is, of course, from a 265-horsepower, 6.9-liter inline-eight. This car lacks exterior door handles from the factory and rides on the shorter of the two main Model J wheelbases. This chassis originally had engine J-145 in it, but it was replaced early on with J-403. The body was originally fitted to the car with engine J-336. By the 1950s, the car as you see it had come together.
