I would look to other sources. Try the the Tennessee State Museum, they have a weapons collection and may also keep track of important pieces as this.

I was seaching for Lady Slocum (heavy artillery used at Spanish Fort, Alabama) for years. I read where she was dedicated at Mobile Alabama in the late 1800s or early 1900s at a memorial to the war. She was nowhere to be found in Mobile. I found her at the front of the Confederate Museum in New Orleans, she had been moved there about the time it was opened.
