Hmmm, I'm 90% sure I know what this is but I'll leave it for now to give our other members some time to join in.

And I bet everyone has been shot down at least once attacking this "Behemoth"

Me 323 Gigant?

The gun is Russian, so I think it's a Pe-8.

Well done it is the mid upper turret on a Pe-8
