Checking out the mess...

looks like the guy on right may have got a rifle butt to the head?

German POWs

Produced by Factory No.100 at Chelyabinsk (ChKZ)

The Urals became a centre of tank production after the evacuation of the Kharkov, and parts of the Leningrad, production, and later from Stalingrad. The new tank factories were set up to take advantage of a vast tractor works built in the 1930s during collectivisation.
Equipment from the tank factory at Kirov was merged with that from Leningrad. The Ural-Kirov Tank Factory in Chelyabinsk was set-up by the People’s Commissariat for the Tank Industry to produce T-34s.

The Kharkov Locomotive Factory were moved to the Uralmashzavod (Ural Machine Building Plant) in the Urals and merged with the Nishni Tagil auto factory. The whole complex of factories around Chelybinsk became known later as Tankograd.

One of the pieces of equipment inherited from the existing industry was a huge 5,000-ton forge-press. So rather than cast or weld the new 1942 model hexagonal T-34 turret, the Chelyabinsk factory (ChKZ) simply stamped them out from the heated metal plate.    
    
Some pressed Turrets were also used on T-34s from the Uralmash Factory at Nishni Tagil. A total 2670 of these dropforged turrets were made.
