The image shows an old-fashioned sextant in a wooden case. The case is open, revealing the inner workings of the instrument. The instrument is made of metal and appears to be made of wood, with a dark brown finish. It has a circular base with a handle on one side and a spindle on the other side. The spindle is attached to the base with two metal clamps, which are used to adjust the angle of the compass. There is also a small brass bell on the bottom right corner of the case, which is likely used to keep the instrument in place. In the background, there is a display case with other antique items on display.
