To be sure you would have to look at the Inspection Reports from the summer of 1864. Stevenson's Division, AoT was supplied almost entirely with Enfields, Austrian Lorenz, and Springfield rifles during the Atlanta Campaign. I do not have the reports of the other divisions available but I do know that the variety of weapons during the summer of 1864 was considerably narrowed due to the efforts of Joe Johnston and the Army's Ordnance officers. I have seen these reports before but can't quote numbers at this time.
