Tucker turrets

[Johnbr]

Here are a couple of photos of Tucker turrets
One appears to be a mock up while the other looks like a production model.

These must have been real early or just before WWII judging by the guns. The 50 cal guns have slotted cooling jackets and the early vertical style back plate.

What were these intended to be used in?

I read a flying boat do not now which one.
