Octant by unknown zoom


The octant has an ebony frame and limb with a brass index arm, fittings, and a stop for the index arm. It also has an inlaid ivory plate on the crossbar and inlaid decorative ivory strips along all edges of the front of the frame. There is no tangent screw, and the clamping screw, which is missing, is on the back of the index arm. The socket shades are also missing. Index-glass adjustment is made by a screw and both horizon glasses by levers, wing nuts, and milled clamping screws. The sight vane has two pinholes and a swivelling shutter, whereas the back sight vane has one pinhole and is fastened to the brass back horizon glass mount. A pencil or screwdriver, one wing nut, and a clamping screw are missing from the crossbar. The octant has no box.
