Description
This steel instrument has a needle point on one leg and a pen point on the other. A cross-hatched handle is attached to a ring, which in turn is attached to the legs. A screw goes through both legs, with the nut for setting the compass at a desired width outside the leg with the needle point. Additional thumbscrews allow adjusting of the needle and pen points.
The instrument appears to be a Champion Bow Pen, model number 738C, advertised in 1926 by the Eugene Dietzgen Company of Chicago. The leg with the needle point has handwriting: P M LARSEN. Engraved on the other leg is the word EXCELLO and the Dietzgen logo.
