Looking at the last views this T-34/76 is at:
Vadim Zadorozhny Museum, Arhangelskoe, Moscow Oblast (Russia)
Translation of the last words in the video:
"At the 27th april of 2010 this T-34-76 was sent bu railway to the Salekhard city" (this is the city at the nord of the Russia)
I assume the assorted pieces were from the catastrophic destruction of at least one tank, if not more.
Parts for this tank are parts of many other destroyed tanks.
He looked for them at the last several years.
The hull is a 1940 hull with the square engine access hatch in the rear hull instead of the later circular one
Such rear decks were produced until the summer of 1942 (STZ).
The turret "Gayka" and such rear deck is incorrect, but this is possible for repaired tank.
Does it run, by any chance?
It will never be running.
They made empty hull, without of suspension' shafts.
It will be too difficult to made it running.
