Naval Gun Load for F-22 Flat Car

This model complements the F-22 flatcar I previously posted at the following link.

The model is of a Naval Gun that would have been transported on 3 of the F22 flatcars.
I intended the gun sections to be mounted on a 26.7" section of 1/2 SCH 40 PVC pipe.

Following is a link to a website with images of the F-22 Flatcar transporting naval gun
