This is a mariner's sextant. It is stored in its case when it was not being used. The instrument was hand-held.
A sextant was used for measuring the angular distance between the horizon and a celestial or landform object by using the double reflection of two mirrors. It was used in conjunction with tables and triginometry that allowed one to determine one's latitude, usually at sea. Marine sextants were also useful for deducing the height of shoreline land forms (e.g. head lands) while one was still out on the water, which was useful for coastal navigation.
