We know the 85mm turret is smaller than it should be. The 85mm turret is the size it is because the tank is a model mix, the chassis was resized to fit on Cromwell tracks, this means the T-34 in game is slightly smaller than irl, so a turret modelled off blueprints isn't going to match up exactly, so the turret had to be resized also. It would have been possible to resize the 85mm turret but we we're aiming for the initial release so we left it until after. I'm looking into the models, see how they can be improved.Also, T-34/85 upgrade only works on Tanks built AFTER you have upgraded, it is not global.
