Ken,
Thanks for the additional details. I was not aware of the BF that they donated and is now missing. The museum curator at Manassas told me that these flags were donated to Kennesaw Mt NBF and then sent to Manassas as they were more pertinent there. The family was in Georgia at the time of the donation.
Boy -this regiment sure has loads of flags including the two homemade ANV style colors!
