Artillery Musician's (Bugler's) shell jacket, manufactured at the Schuylkill Arsenal in Philadelphia.

Regulations called for musician's uniforms to match the coats worn by other enlisted men of their respective branch of service, but with the addition of a twill lace facing running across the breast, placed on a line with each button. The design was to gradually widen toward the armpit, and narrow again as it approached the collar. A strip of the same lace following the outer extremity of the bars created a ribbed "herringbone" form to the pattern.

This jacket shows a brilliant red piping with plaid lining typical of many jackets of Schuylkill Arsenal manufacture. The left sleeve bears the SA contractor's stamp and the four-dot size marks. The right sleeve bears an additional four-dot imprint. All matching eagle artillery buttons are original to the coat.
