Thomas Emberson of Long Sutton (Lincolnshire) - Early 19th century longcase clock c1810 with a 30hr movement and an exceptionally rare 24-hour painted dial, housed in an ebonised Pine case with a flat pediment and break arch hood door, glazed side panels and turned pilasters with brass Corinthian capitals, trunk with a long door and conforming break arched top raised on a stepped plinth, fully painted dial with painted spandrels representing the four seasons and an operating automata depiction of ships at sea, rising and falling with the time of high and low water to the arch, with a 24-hour chapter with Roman numerals, five minute Arabic's, minute and inner quarter hour tracks, steel radial minute hand and image of the sun recording the hours, secondary inner dial illustrating the phases of the moon and lunar calendar recording the date and times of high and low water at Fosdike Wash (Lincolnshire), with an adjustable circular disc to the centre giving the times of high water at seven other locations including the Northern Pacific Ocean, dial attached to a countwheel striking chain driven movement, sounding the hours on a bell. With weight and pendulum.
Thomas Emberson is recorded not as a clockmaker but a machine maker from Long Sutton. This clock is also thought to have originally contained a musical movement, now removed, and was clearly an individual project possibly based on an earlier clock by John Ferguson illustrated in "Select Mechanical Exercises" published in 1773.
