Pure speculation on my part, but I tend to think they carried another first national, not a nice one like the presentation piece captured at Donelson, but a plain bunting one. Part of this comes from looking into their sister unit, the 26th TN. I have an account where a member of the 26th stated that they cut up their Chickamauga flag to make the unit designation for their Dalton issue battleflag. Their Augusta Depot flag issued at Dalton has white 26 and TN sewn on it. For that much pure white I think it had to be a 1st National, but I could be wrong.
