Keuffel & Esser Pocket Compass

<< >>
Usage conditions apply
This compass has one folding sight; a slit in the lid serves as the second sight. Since the lid is mirrored, the user can read the needle while sighting a distant object. The floating card is graduated to degrees and numbered every ten degrees to 360. There is also a second (inner) row of numbers in quadrants, reversed for reading in the mirror. The signature reads "KEUFFEL & ESSER CO NEW-YORK" and it probably dates from the period 1890–1910. Keuffel & Esser donated it to the Smithsonian in 1972.
