Hi Ken,
Below is a link to a website that shows a rendering of the flag that Bright sketched.

I do not have an actual copy of the sketch that he sent home to Martha (his wife) in his letter. Would LOVE to see it! I would also love to find copies of the rest of the letters to read. They are pieces of history that are so very precious in learning about the people I came from. Are you related to the Burrells or are do you have interest in the 1st South Carolina Cavalry Co F?
Take care,
Addie
