Kubinka Tank Museum
In the early 1940s an attempt was made in the Soviet Union to mount the 130 mm B-13 gun on a tank chassis. After Winter War one of the T-100 tank prototypes was refitted with a hull mounted 130 mm B-13 gun. This vehicle was known as SU-100Y and the prototype was used in action during the Battle of Moscow. The prototype survived the war and is now on display in Kubinka Tank Museum.
