The Tatra T57 was Tatra's best selling and most popular personal vehicle. When the Germans seized the Sudetenland in 1938, German authorities seized the factory and stopped all production of the T57 and other Tatra vehicles but by 1939, this issue was resolved in Tatra's favour. The Czech automotive press and general public were delighted when the T57 was approved to go back into production and sale across the Reich. https://tatrat600.blogspot.com/2022/08/1939-update-on-tatra-manufacturing.html
German civilian car manufacture was banned in 1940, but the Tatra plant continued production of the T57 and T87, albeit in small numbers. In order to keep the civilian T57B in production, Tatra's managing director, Hans Ledwinka, obtained a contract to build a military version of the car. This version was designated the T57K, meaning kubelwagen, which was a generic term for a military 'bucket seat' car. The T57K featured the standard slab-sided body panels common to almost all Germany military vehicles. Seats and fittings were spartan. This variant remained in production throughout the war and continued post-war in small numbers for the Czechoslovakian military.
