AN EXCEPTIONAL 8IN. RADIUS VERNIER SEXTANT BY WILLIAM DOLLOND, LONDON, CIRCA 1860

the lacquered brass and partially oxidised T-frame retaining most of its original finish, the arc signed Dollond London and inscribed Silver above '70' with inset scale divided to 145°, vernier with magnifier on horizontal tangent screw adjustment, and glass light diffuser, braced index arm, mirrors and seven shades on oxidised frame section, handle with stand clamp accessory and three pin feet, contained within fitted keystone box of issue with complete accessories including five eyepieces, filter and pin, with maker's label inside lid, and securing hook -- 14in.

William Dollond (1834–1893) was the last of this famous family of makers and, upon his retirement in 1871, a dispersal sale was held on the premises by Winstanley & Horwood at which the contents were sold from the 8th of August in a sale lasting several days. The outstanding original condition of this instrument suggests it may have been part of this sale.
