AN IMPORTANT AND POSSIBLY UNIQUE 9¾IN. RADIUS MAHOGANY AND BRASS PROTOTYPE DOUBLE-FRAMED VERNIER OCTANT BY EDWARD TROUGHTON, LONDON, C.1782-5with curved bar frame, the arc with brass plate supporting seven pillars with raised brass scale divided to 120°, signed Troughton London, Vernier with clamp, secondary window with tangent screw adjustment, secondary free Vernier cursor punched `-15°`, brass index arm, sighting tube, two mirrors and three shades, contained within original stepped keystone box with lock plate and key (knob of tangent screw detached but present) — 13 x 14½in. (33 x 37cm.) The Troughton Family (John Troughton Snr. 1716-1788, uncle to brothers John Troughton Jnr 1739-1807 and Edward Troughton FRS 1753-1836) achieved world-wide fame for the division of scales on sextants. Realising that fluctuating temperatures caused the metallic expansion and distortion of their precision-divided index scales, they corrected this with double-silhouette sextant plate frames. Conjoining both frames together by riveting small brass pillar-stays of about 10mm., they created the double-frame structural rigidity required to avert temperature distortion of both the frame and index scale divisions. This sextant is thought to have the earliest Troughton signature witnessed on their instruments and an example of one of their primary attempts at averting such scale expansion. John Troughton Jnr. patented his double-frame in 1788 and once perfected, the firm produced many fine all brass examples purchased by the East India Company amongst others.
