Bow Compass
date: label: date made
content: ca 1900
notes: label: Description
content: This steel-spring instrument has a metal and ivory handle, with a ridged ring around the bottom and the top shaped like a pawn chess piece. A holder with a metal adjusting screw on one leg is missing its needle point. This leg is marked with the number 8 inside a circle and an arrow pointing left (toward the 8). The holder on the other leg has a pencil lead and is adjusted with a brass screw. The distance between the legs is adjusted with a metal screw and brass nut. This object does not resemble the ivory-handled bow-pencils sold around the turn of the 20th century by Keuffel & Esser, Dietzgen, Gurley, Kern, or Schoenner.
