Кировский завод
According to Russian historian Maksim Kolomiets in his book "T-28. Stalin's Three-headed Monster", over 200 T-28s were knocked out during the Winter War, but only 20 of them were irrecoverable losses (including two captured by the Finnish Army). Due to the proximity of the Kirov Plant, all other knocked-out tanks were repaired, some of them more than five times.
