All I can tell you is that I asked a question at a museum on an Army Base umpteen years ago how much would one of their flags cost if is was auctioned off and was told 20 years. I was also told that all U. S. Military flag belong to the U. S. Government and that Civil War period flags are a iffy subject.

Seems like it would be a good question to ask the Military legal eagles.

Happy Trails!
