Look at the "DEPARTMENT OF ALABAMA JACKETS"...
"All of these jackets are made of woolen jean, with a six piece body and two piece sleeves. All have linings of cotton osnaburg, and all have collars made of dark blue wool jeans, (dark blue woolen weft on a brown cotton warp). All have five button fronts, and all have one exterior pocket, though they vary from one side of the jacket front to the other. Two have small single belt loops, shaped like shoulder straps on the left side only. One is missing the original buttons, one is missing all its buttons, but the remaining two are equipped with wooden buttons like those seen on the Columbus jackets. Taylor's main source of supply, particularly to troops on the Meridian, Mississippi- Mobile, Alabama line appears to have been the large depot operating at Columbus, Mississippi. In July, 1864, the Quartermaster there, Major W.J. Anderson, was disbursing approximately $130,000 per month. He boasted that "...The clothing material is excellent and the workmanship superior to any I have seen made elsewhere..." The depot at Columbus was operating as late as November, 1864, but by 15 March 1865, Anderson was being listed as a "Manufacturing Q.M." at Demopolis, Alabama. It is therefore possible that the jackets described here were made in either Columbus, Mississippi or Demopolis, Alabama."
