The musket/rifle is shown in a photo, taken sometime after Nov. 1863, of Private Thomas Taylor, QM Dept., Montgomery, Ala. The photo is shown in the book "Echos of Glory: Arms and Equipment of the Confederacy" on page 141. If you have this book, please take a look at the photo and see if you can identify the musket/rifle. It appears to me to be a Austrian M1842 Infantry Musket/Rifled Musket.
