here is the upcoming Czechoslovak tier 9 Škoda T-50.
The TVP medium tank program continued from 1946 to 1950 with a number of proposals made by both Škoda and ČKD. In 1949 the Škoda proposal received the official designation of T 50. The turret was changed from a welded one to a cast one and the vehicle was proposed to be armed with several 100mm gun variants. The main feature of the proposal was its extremely high mobility provided by a proposed 1000hp engine. Several components for this vehicle (such as transmission) were built and tested but a prototype was never completed. In early 1950, the Škoda T 50 and Praga T 51 projects were unified into one, effectively ending the independent medium tank development by Škoda.
