Antique 1860s Ambrotype Photo Of Armed Civil War Soldier Holding Painted Sword

1/6 ambrotype, soldier with painted gold shoulder boards, buckle and buttons, tinted pink cheeks and lips. On the table next to him is his shako with tinted red plume. I can't quite make out the words on the front or the insignia...

Might be a musicians insignia OR a 75? I've provided a closeup, (mirrored scan). Comes in full case with separated, matching covers.

Clear glass ambrotype with painted back glass, behind mat and original glass. Very good antique condition as shown; my scan came out slightly blue tinted, actual color is a shade greener.

A nice Civil War image.
