This Maybach SW 38 was delivered to the Thyssen Group in Düsseldorf on April 21, 1938 and registered with the registration number 'IY 14346'. Originally the chassis was fitted with a gray-green Pullman limousine body from Spohn.

Not much is known about the early years and the war time. In 1948, however, the car was transferred to Thyssen-Gas- und Wasserwerke Duisburg and returned to Maybach Motorenwerke in 1950. Spohn received the order to re-equip the car with this modern pontoon structure. On this occasion, the chassis was completely overhauled and equipped with a new 4.2 liter engine (engine number 11719). This body was Spohn's first pontoon convertible after the Second World War and remained a one-off. The work cost an enormous 38,000 DM in 1950.

In this version, the car went to the construction company Kahlmann & Co from Hamburg in 1955. In 1961 the vehicle was deregistered. A few years later it was rediscovered in an estate and finally it ended up in the Maybach Museum in Neumarkt, where the car can be admired today.
