A George III mahogany eight-day longcase clock with rolling moonphase incorporating tidal indication John Baker, Hull, circa 1780 The four pillar rack and bell striking movement with anchor escapement regulated by seconds pendulum, the 12 inch brass break-arc h dial with subsidiary seconds dial, calendar aperture and ringed winding holes to the matted centre within applied silvered Roman numeral chapter ring with Arabic five minutes to outer track, with scroll-pierced blued steel hands and rococo cast spandrels to angles beneath arch with rolling moonphase signed IOHN BAKER HULL to upper margin and calibrated for age of the moon and high-water times to the circumference of the lunar disc over lunettes engraved with globe delineations flanking two adjustable blued steel pointers to centre, the case with gilt Ho-Ho bird centred oval fretwork panel to the pagoda upstand over hinged glazed dial aperture flanked by free-standing Corinthian columns, the trunk with rectangular flame-figured door with concave-cut upper angles and flanked by fluted canted angles, on figured plinth base with ogee bracket feet, 228cm (89ins) high. John Baker is recorded in Loomes, Brian Watchmakers & Clockmakers of the World, Volume 2 as believed working in Hull, during the late 18th century. The current lot is perhaps a little unusual in having two steel pointers within the moonphase; the first is intended for the age of the moon whilst the other can be adjusted to provide the times of high water for a given port to be read from the scale engraved to the edge of the disc.
