Not sure about the Khaki belts, but as far as the Blue Campaign Shirts go
they were used by State Forces as well as Regular Army Troops.
I'm not sure how much of a help I can be but if you have any questions
feel free to email me. I remain, as always,
Your Faithful, and obedient, servant,
Kenneth H. Robison II,
