The Army Prescription Balance was a simple and inexpensive brass instrument that fit into and stood on a wooden box. The form was available by 1880. In this example, the beam is 8 inches long, and marked “7”. The brass label on the box reads “HENRY TROEMNER / MAKER / PHILADELPHIA, PA. / CAP. ½ OZ. NO. 9 / MADE IN THE U.S.A.”
