WWII Soviet tank memorial stock #2

This old Soviet tank has been through World War II and during some fight in Southern Russia it was hit and sank down to a river's bottom with its whole crew inside.
Half a century later, a phone cable laying, overseen by my dad as a head engineer in late 1980s, went through the same river, and the tank was found along with its dead crew. They were lifted from the bottom of the river and buried, and the tank found its final resting place atop a memorial built for WWII heroes. When I was a kid, I often played on it, because our house was in the first row next to the memorial square.

My dad told me, that when they first opened the tank, there was still air in and smells in it, trapped back from the 1940s.
