I had a nice book on several flags, till about 12 years ago one of my sons tore the rebel flags out and the book was never found but the flag pictures were saved. It just had the flags and just as I wrote in the first post what was next to them. I dont know anything else on these flags.
I am looking at the pics right now it says "Austin's Batt" They fought with this flag during the Atlanta battles. They fought around the Pope House west of the city. The page number is 273, the book is lost in history.
Sorry I cant be more of a help,
