Thank you for your link to the "CIVIL WAR SOLDIERS BRADLEY COUNTY, ARKANSAS", it had a nice little snippet about an early uniform for Co I, 2nd Arkansas Infantry Regiment.
If you note anymore such items in your perusal of original documents I would be glad to hear from you, my email is info@confederateuniforms.org.
By the way, have you come across a name for Co I, 2nd Arkansas Infantry Regiment in your research, Tancig only lists four named companies for the 2nd and Co I is not one of them.
