Hi Shawn,
Have you read the late Richard Rollins' book "The Damned Red Flags of the Rebellion," which is an analysis of the CS flags lost at Gettybsurg?
He has a chart at the back of the book that lists 59 captured CS flags. He does have ten CS flags taken on July 3rd that are currently in unkown locations.
I will pass along the Union flags information and psot it on the GDG and see what turns up.
