"T-34-57"

Out of the many resilient myths that surround the T-34 tank, there are several that revolve around the rarest one of them all: the T-34 tank armed with the 57 mm ZIS-4 gun, specifically the four experimental tanks produced in 1943. Many sources give these tanks and their guns some kind of made up name like T-34-57 or ZIS-4M and claim that these tanks fought in "special tank company #100" from August 15th, 1943. All three of those claims are false.

"Act

On August 18th, 1943, we the undersigned:

• representative of the Gorohovets ANIOP Guards Senior Lieutenant-Technician A.F. Platonov

• GBTU military representative at factory #183 Lieutenant-Technician Belyanskiy
• commander of T-34 tank #36-322 Lieutenant G.S. Romanov

compose the current act to record that, during the breaking in and firing on the move trials of the ZIS-4 gun mounted in a T-34 tank at the Gorohovets ANIOP the following defects occurred after 200 km of travel:

1. The air thermometer did not show water temperature. The thermometer was replaced with one that arrived from factory #112.
