Compass in Case
date: label: date made
content: early 20th century
notes: label: Description
content: This six-inch German silver instrument opens into a double "V" shape. It has a cylindrical handle, thumbscrews for removing the point attachments, and thumbscrews for adjusting the points. The legs may be fitted with any combination of a needle point, two lengthening bars, a pencil point, and a pen point. The second needle point is missing. The lengthening bars extend the compass horizontally to a width of 9-3/4", allowing the instrument to function as a beam compass.
label: Description
content: Almost all of the pieces are engraved with the number 60, except for the pen point and one lengthening bar, which are each engraved with the number 61. It is possible that some of the pieces have gotten mixed up with those catalogued with 1978.2110.04. A wooden case is covered with burgundy-colored leather and lined with black velvet.
