Historical reference
The AT-1 tank destroyer based on the T-26 light tank was developed by the construction bureau at the Experimental Design Mechanical Department of Factory No. 185 in Leningrad from 1935 through 1936. The vehicle was designed for anti-tank warfare. Two prototypes equipped with the 76.2 mm PS-3 tank guns were built, which underwent trials by 1936. This vehicle never saw mass production.
