If I’m reading your question correctly your looking for a November 1861 silk issued battle flag. If you contact the Museum of the Confederacy in Richmond and ask for a picture of the 1st Virginia Infantry silk ANV Battle flag (moc # 0985.13.923) it should make a good representation of the 7th, 11th or the 17th silk ANV, since those flags are not known to survive. The silk flag was replaced in May of 1862 by the 1st bunting ANV. That's the one with the honors "Williamsburg" & "Seven Pines" survives. The 2nd bunting issued in July 1862 undoubtedly carried until the spring of 63, what became of it is unknown. Pickett's brigade received a third bunting Richmond issue while on the Suffolk Campaign, these had white paint unit designation in the staff quadrant and "Va. Infty" in the fly quadrant. Some of these flags were not surrendered: unfortunately I do not know their locations. The ones that survive do not have honors on them, and some do not have unit designation which makes it hard to ID.

Happy Trails!
