David Stalker sextant rare image

Fan shaped Case!

very rare design using two vertical braces (columns) in the Ebony frame rather than the single center brace which was
almost universally adopted. It was made by David Stalker of Leith and has his perfect label on the inside of the cover. The
design features an ebony frame with carefully graduated ivory 

arc and vernier,  bronze fittings and both a sighting tube and telescope. The arc measures from – 5 to plus 105
degrees. This two upright braced frame has a brass index arm measuring 10 3/4 inches long, with an
early style ivory vernier scale, reading from right to left from 0 to 20 arc minutes with magnifier missing, four sun
shades, three horizon shades, an index and horizon mirror and two sighing tubes. The company, located at 6 Commercial
Place, Leith, is listed in Webster’s Registry of Instrument Makers as making octants, compasses and barometers during
the 1860’s.  Only a compass with this name is at the National Museum of Scotland which attests to the scarcity of
his work.

POLISHING is available on this sextant at additional
cost which will elevate it to Presenation Grade.  To inquire about polishing this item, =#000000>click here
