The gun housing and mantlet box have been reassembled onto the trunion.
The assembly is ready for placement of the main gun.

The 75mm gun is hoisted into position and centered into the housing.
The 75mm gun is aligned and moved into the housing.

Rick Dickerson carefully inserts the gun tube into the housing.
As with many of the heavy ordnance mounted on vehicles in the Patton Museum collection, this 75mm gun is fully functional and could fire live ammo. However, any firing done of the main weapons is for public displays and reenactments and only blank ammunition is used.
