A single triple-bordered shoulder strap for a captain of infantry. A dead-real Civil War officer's shoulder strap. Some loose threads show it was on a coat. It has some fading to the gold bullion, but still good color to the light blue wool branch of service color.
A nice example of Civil War military embroidery and a good study piece if you are interested in collecting CW insignia and want to get your feet wet without spending a fortune.
