On June 12, 1864, Colonel Armistead (Armistead's Cavalry Regiment) signed for 2000 Enfield rifle cartridges .58 cal, 2000 Mississippi rifle cartridges .54 cal, and 3000 Mississippi rifle cartridges .54 cal for carbines. I assume the Enfields were 2-bands. Were there any cavalry units issued the 3-band? Was there a Mississippi carbine?

Thank you for your help.
