content: This metal instrument has a handle with vertical ridges above a ring. Unlike almost all of the other bow compasses in the collection, the bow screw has tips on each end. A thumb screw on the leg with the pencil point allows for fine adjustments of the angle at which the instrument is set. Screws near the points and on the front and back of the instrument adjust the length of the needle and pencil points. The top of the leg with the pencil point is marked: CHARVOZ (/) GERMANY.
label: Description
content: A clear and blue plastic case is marked with the Charvoz logo and charvoz (/) S - 801. The flap closes in the back and is marked: WESTERN–GERMANY. Inside the case is a clear plastic cylinder holding two replacement pencil leads and a second needle point, allowing the compass to be used as a divider. The bottom of the cylinder is marked: MADE IN GERMANY. A pen point is wrapped in brown paper. The screw on the pen point is marked: GERMANY.
