Cooke (Hull) Marine Sextant 1970

Cooke (Hull) Marine Sextant 1970. A very good marine sextant by Cooke (Hull) with a 6x30 monocular (non-reflective coated optics) viewing scope. Number 3353 and correctly certified in its original mahogany carry-box with handle.

Catches work well but key is lost. The instrument is intact with a very good index mirror complete with 4 swinging index shades (glass all good). The split horizon mirror is excellent with 2 swinging horizon shades (glass good).

The index arm (with the Cooke logo plate) operates smoothly with a good release catch/locking device. The thimble, micro-meter drum and vernier scale all work correctly.

Gearing on the arc is good. The monocular armature can be adjusted on a slide by loosening the thumb screw. Focus of the monocular is smooth and nicely damped. There is a nut adjusting pin in the case.

32cm x 25cm x 14cm. Cased: 32cm x 29cm x 16cm. The instrument and case are in good clean working order.

There is slight working-life corrosion to the instruments screws and nuts. A lovely working instrument with a superior monocular scope. Please examine photographs as these form part of the condition report. Heavy item to securely P+P.
