Description

Extremely fine (as new) anodised/bright brass sextant with silvered scale running out to 150 degrees and engine divided to 1/10 degree and vernier with magnifier taking that to one arc second. Cased with all of it’s original eyepieces (sighting, low and high power and long tube with multi block cross hair grid. Separate sun shade (dark) filter also in case. 

This instrument is missing zero anodization/enamel or lacquer and has never been touched other than to refinish and re-line the mahogany case (with owner’s initials). The condition can only be described as new old stock. Certificate of accuracy dated to 1891. Ebony handle, all filters intact, mirrors are perfect as well. The silvered scale was oxidised black so I cleaned it just enough to highlight the scale divisions and the signature. The address is very rare as it indicates their (Gray and Keen) primary address of the Strand (all recorded instruments using 23-25 Strand) but also the nearby and parallel address of Canning Dock (see map of Liverpool c.1890, last photos).

This is an exceptional instrument for the connoisseur collector. There is not a scratch to be seen. If you wish additional photos in daylight, I can post more or individually to your email address. 

The sextant has a radius of 7 1/2 with an arc circle of 10 inches. The mahogany case (with all brass L- hooks and handle) measures 10 1/2 inches square by 5 inches deep (refinished).
