Antique Sextant 1913 Certified In Original Case With Telescope And Attachments

The angle, and the time when it was measured, can be used to calculate a position line on a nautical or aeronautical chart. Sighting the height of a landmark can give a measure of distance off and, held horizontally, a sextant can measure angles between objects for a position on a chart. !
