It is said that Omsk plant was transfered from STZ. But details are not known. Some people say that T-34 producted in Omsk is exist. But Omsk original features are only small angled fuel tank and single type handrail. And in these tanks, there are many variations in details. So we can consider that Omsk plant only repaired and reproducted T-34s in this period.
But this plant seems to have been a big repair plant and systematically repaired huge amount of T-34s.
