Epaulette Insignia
Epaulette Circlets for the 4th and 25th Infantry Regiments
These circlets were pinned to the surface of the epaulettes. Higher numbers, such as the 25th regiment, are for state forces and lower numbers could be Regular Army or state forces. Circlets are of two types:1) flat (such as those above) and 2) domed. Notice that the blue of the circlet with the number four is a deeper blue than the other. This kind of color variation is common with Civil War insignia.
