Actually I don't think the way the parts go together is correct. The way I understand how the turrets retracted into the fuselage was the platform the ring gear is all part of had hinges on one end and an elevating mechanism on the other. The platform then swung down so the turret tops would end up facing each other once retracted. But that won't happen with those ammo boxes just below the turrets here.
In the photo below you can see what I mean, the turret ring platform is hinged on the structure sides and knee-braces attached further down the structure side and then to the other end of the turret ring platform. The knee-braces fold in half during the retraction and the platform just swings down. You certainly wouldn't have those posts sticking up and the ammo bins would have to be further down or in the other end of the turret bay. I also think the ammo bins would have to turn with the turrets otherwise the ammo belts would soon get tangled up --
Unless I'm missing something here ---
