Ok, thanks! Missing top turret? It looks like it's there...

It obviously has the exterior glass part, but there's a rotating cylindrical
metal stand for the gunner inside the plane which is part of a functioning
turret. Perhaps that's what's missing? If so, you'd need a small ladder to get
your head up into the dome.

The ball turrets also had lots of hardware inside the plane. Some restorers
remove this stuff to make it easy for people to traverse the plane. It was
pretty cramped inside a fully functional B-17. Without the interior hardware,
the turrets can't rotate.

Drink is the curse of the land. It makes you quarrel with your neighbor.
It makes you shoot at your landlord. And it makes you miss him.
