Though the original has never been found (was most likely scrapped), there are several tribute cars that have been built, including this one in South America:
Gordon Beuhrig was a famous car designer. Beuhrig's Model "A" began its existence as a Cabriolet. He modified it to mimic the Duesenburg Model J which he designed.
Interview with Beuhrig - page 15: Before I got delivery of it, I had made a full-size body draft of it--what I wanted to do--and made arrangements with Augie Duesenberg at his race car shop to build the body for me. I drove the car from the dealership out to Augie's place, and first thing we did was take the body off the chassis. Then, we cut the body back of the body B post, which is the back of the door, and that rumble seat (all that area), we threw that away and kept the body frame sills, and we mounted the body back on the chassis 4 inches aft of its normal location. Then, we built a dummy cowling, or extended cowling, so that the fire wall was moved forward into its normal location in relation to the engine. Then I had to build a new engine hood which was 4 inches longer than the regular engine hood. Then the back of the body was all new, framed in wood, and paneled in aluminum, and it extended just a little bit beyond the rear axle, and then I had a large trunk on the back, and on the inside I had a single seat facing the center. The passenger seat was built so it would fold forward so that you could get into that rear, one-passenger, enclosed rumble seat. It was a blind quarter convertible--beautiful thing. I lowered the--cut the windshield down to the top of the upper hinge on the door, and that I think was 31 inches. So, the body was 3 inches lower than the regular Ford. At that time the Weyman Body Company was going out of business, and I bought some of their hides of leather for $5 a hide, and when Augie was through with it, we moved it across the street to the Duesenberg plant where they allowed me to have it painted and trimmed by the head trimmer and the head painter at Duesenberg. We did have a good paint and trim shop.
