This steel and German silver instrument has a needle point on one leg and a holder for a pencil lead on the other. The handle has vertical ridges above a single line of raised metal dots. The width of the compass is adjusted with a pin through the legs and a wheel around the pin between the legs. Additional thumbscrews allow adjusting of the needle and pencil points. The instrument appears to be a Federal Bow Pencil, model number 736B, advertised in 1926 by the Eugene Dietzgen Company of Chicago.
