Removal and Condition of the Gun Cradle (cont.):
The traverse arc gear was found to be heavily corroded.
The traverse drive gear seen under the gun cradle in the image below was similarly very corroded. Just below the drive gear and to its left and right are two corroded steel cylinder rollers that bear the forward weight of the cradle but allow traverse movement.
The bottom of the cradle (the sides as well) is constructed as a hollow steel box. Three walled holes provide rigidity to the hollow box at these points.
