i've never seen one. On the website confederate flags.org and another is information about Lorings division flags. Lorings division contained 2 Mississippi brigades and one from Bama. THere flags were second nationals with with no white stripes bordering the blue cross. Check out the flag of the 33rd Mississippi for a replica. These second natioals were only issued in 1864. Prior flags are unknown to me.
Take care!!
