Thanks Gregg, that was my question about all USCT units in the western theatre: BTW, I went to the Travellers Rest Symposium today and posed the same quesion to Dr. Lovett.
He knows of no USCT flags that survive, at least in the West, but I have seen photographs of several original "eastern" USCT regimental flags that are very ornate and I know that at least some of them carried both colors. Maybe the western federal army was in the same predicament as the Army of Tennessee was to the ANV ...........always a bridesmaid to the Army of the Potomac.
