The case surmounted by a pierced dome cover , above which is a figure of Fortune. Finials above the columns. All four side panels of the case are glazed and removable; the brass dial is mounted on the outside of the front glazed panel, which measures 10.2 x 5.7 cm. The rear panels has two drilled winding holes, for going and striking, and the right-hand panel one, near the bottom,for the alarm. \r\n\r\nDials: The engraved chapter ring is 6.0 cm diameter, with Roman hours with touch-pins and half-hour marks. Inside this is a revolving silvered moon disc with a ring of figures 1 to 29 and the phase shown in the circular aperture of a superposed brass disc 3.5 cm diameter numbered 1 to 12 anti-clockwise in arabic to the outside of which the steel hour-pointer is attached. The moon disc moves friction-tight with the brass disc but has four drilled holes at moon ages 2.5, 9.5, 17.5, and 25.5 for hand-setting.\r\nThere is a short central iron hand for setting the alarm.\r\nBelow the main dial is mounted a dial 3.2 cm diameter marked in Roman I, II, III, IIII with a simple brass hand with tail rotating once per hour. \r\n\r\nMovement: The frame consists of four sqaure corner posts, top and bottom plates with a further plate just above the top plate, and three vertical movement plates not of the full width of the frame. The upper top plate is signed:  15  BS  80.\r\nThe going train is mounted in the front half of the frame. Engraved brass barrel, brass fusee and wheel, chain drive. Verge with attached \"bob\" pendulum now missing. There is now no sign of the centre plate of a potence for the lower end of the former vertical verge. \r\nThe fusee rotates once every 4 hours, and has 6 turns. \r\nThere are two dial train outside the front plate.\r\n(1) To the quarter-hour hand. A 40T wheel on the fusee arbor drives a wheel of 20T with two projecting pins which let off the hour-strike. The 20T wheel drives a 10T wheel coaxial with the quarter-hour hand (rotating once per hour) through an idle 10T wheel.\r\n(2) A 20T wheel on the fusee arbor drives a 60T wheel coaxial with the hour-disc and hand (1 rev. every 12 hours). The moon disc is coaxial through a sleeve with an untoothed brass disc which is partly inserted into a recess in the 60T hour-wheel and rotates friction-tight with it. There is now no moon gearing, though it could be added quite simply with the aid of a 59T wheel. \r\nThe locking-plate striking train has an engraved brass barrel, a brass fusee of 6 turns and brass wheels. The outside count-wheel is driven by reduction gearing from the arbor of the second wheel of the striking train. This arbor and the third arbor of the same train are of turned baluster shape. \r\nThe alarm train, low down at right in the front half of the movement, is wound from the side of the case. Its release mechanism is not quite complete.
