content: The instruments in the cardboard box appear to be a mix of products of Copp, Clark Company with other drawing instruments. They may come from more than one set. Instruments in the box include two identical wooden 30-60-90 triangles, marked with inches along the two shorter edges on one side and centimeters along these edges on the other side; as well as a wooden isoscles right triangle, again marked with inches and centimeters along the shorter sides. The two identical wooden proportional rules are marked: THE COPP CLARK COMPANY. In addition there are two identical semicircular protractors made of tin and divided to degrees. Two metal dividers and a drawing compass also would appear to be part of the set. Also in the box are a brass folding set square, a pen point, and a wooden and brass parallel rule with brass hinges.
