AN UNUSUAL 7IN. RADIUS SEXTANT POSSIBLY BY C.J. KETTLEWELL, CIRCA 1860
the three-circle oxidised brass frame with polished arc signed as per title and inset with contrasting black composition inset with a white scale divided to 150º and stamped PATENT COMPOSITE ARC, braced index arm with vernier and magnifier, seven shades, two mirrors, pin feet and wooden handle, contained in possibly associated lined box with three sighting tubes, drop handle and securing hooks and trade label for 'Frederick Smith, Southampton' - 11in. (28cm.) wide
Apparently an unrecorded maker, it's not certain whether C.J. Kettlewell was the maker or an owner - no location or address has been provided as is usual for a maker and this form of arc is possibly unique at the time of writing. It seems to be an attempt at a time of transition from wooden instruments with their easier to read scales to all metal ones with silver scales which in time can be polished away.
