One other point. Confederate Junior and Senior Reserves were authorized by a law passed by Congress on Feb. 17, 1864. The company enrolled by Capt. Truss could not have been organized for reserve duty because it organized several moths before the law, Sept. 4, 1863.
Companies on duty with the Conscript Bureau like this one were not supposed to include able-bodied men who could have been in actual combat units. Conscript Bureau companies like this one were recruited for what we would call military police duties today. Barbiere's Cavalry Battalion may not have had a flag, most of its companies don't seemt to have worn regular Confederate uniforms or equipment, and serviceable firearms would have been scarce among them.
As I mentioned, one of my ancestors beloned to the same company. These were not picture-book Confederate soldiers.
