The serial numbers on the sextant, the identifying plaque on the box, and the Inspection Certificate all match. The following items are included. The sextant with its telescope. Screwdrivers – one Yankee #90 and one Yankee #95. Bronze thumbscrew-style adjusting tool. Mahogany plywood box with all hardware except the key to the lock. A “Certificate of Eccentricity” dated 3/21/1945. A 30+ page manual covering maintenance and overhaul specific to the USN Mark II sextant. Sample page shown in last photo. The sextant arm and its micrometer mechanism operate smoothly and the arm moves throughout its range without binding. The installed mirrors are in good condition. There are no spares for either mirror. The polarizing filters work, but they aren’t in great shape. There is some “fuzziness” to both and the index mirror has some light leaks around the edges. The black anodizing on the frame and telescope is unblemished. The telescope optics are clear and the focusing ring rotates smoothly. A couple of the small set screws are missing but this does not affect the telescope’s functionality. The box is in decent condition for its age. The veneer is worn in places and the edges and corners show wear. The photos show all six sides of the box so you can evaluate its condition. All in all this is an almost. WWII vintage sextant, in generally very good condition. Only the key to the lock and the spare mirrors are missing. The sextant will be VERY carefully packed. I’ve tried to be complete and to disclose all problems, but I may have missed something. Please check out all the pictures and do not hesitate to ask about anything.
