Skoda T-15

The Škoda T-15 was an experimental German-Czechoslovak light tank developed by Škoda Works for the German armed forces from 1941 to 1943. The T-15 never entered mass production or combat, and only no more than five prototypes – including two in mild steel – were built.
The T-15 weighed 11–13 tonnes, and was armed with a 37mm gun and MG 34 machine gun.
