Officially adopted in April 1864 to be worn by Officers and men of all the regiments of the corps, this acorn-shaped badge was commercially manufactured and sold by sutlers in the field and in stores. This example made of brass with one of the brass pins remaining on the back. Measures 1.25" high by .75" wide and has a minor chip along the edge. Recovered this past fall near the New River Gorge Bridge, Route 19 in West Virginia.
