The mahogany box has two hooks for closure and a key hole on the front, as well as a handle on the left-hand side. On the interior, the box is covered in green padding material. The lid has a manufacture note and instruction plaque (see Inscriptions). The sextant has a "HUSUN Trademark" mark on it, and is inclusive of accessories including key tied to a string, cloth and a small Glass bottle of whale oil. The sextant has a black powder-coated finish, whilst the traditional inlaid silver scale is marked from -5 to 150 degrees in single increments. It has a mirror adjusting tool and a screw-on eyepiece sun filter. The word 'sextant' was developed from the actual arc of the frame which occupies a sixth of a circle, and it was a development from the octant. The need to have an instrument measuring up to 120 degrees arose from the observations determination of longitude. The sextant is useful to read horizontal angles and, its all metal construction makes it more accurate than a wooden octant (Baddeley 1993: 50).Navigation and Timekeeping / Magnetic and Astronomicalhttps://emuseum.heritagemalta.mt/objects/889/rdf
