More photos are needed especially the hoist end. There should be a makers mark such as Bull Dog which was one of the major makers of UCV flags. What is the flag made of, silk, cotton etc. Also the the markings on the flag are suspect as most of the UCV flags had State Divisions or camp names and numbers and not units. Not saying it not authentic but need more photos. These flags have been faked in the past so caution is recommended. The fringe seems to be in very good condition which is suspect.
There’s no makers mark, the flag seems to be made of cotton and the hoist end canvas, it measures 34”x 20 3/4” with the fringe, the stars are sewn on, I don’t know what to make of the round marked disc attached to the hoist end rope, despite the bright colors in the photos I must say they are more dull with some fading in person, NOTE: no brass grommets on hoist end, I’m thinking the flag was not meant to be raised on outdoor pole but instead spent its life inside a veterans hall on an indoor wood flag pole with weighted base (I’m guessing this), the fringe is faded but all there, fringe is a light faded tan color, black stenciling is in fact black paint stenciled (not printed), flag feels and smells older than it looks in photos, I’ve included 4 more pics.
