A Victorian mahogany striking table regulator previously fitted with a spring detent escapement Dalgety, Deptford, circa 1850 The five Pillar twin fusee gong striking movement with Harrison's maintaining power and tapered plates now with half deadbeat escapement regulated by half seconds cylindrical bob pendulum, the 9 inch circular silvered Roman numeral dial with subsidiary seconds over Roman numeral hour dials and inscribed Dalgety, Deptford to centre within outer Arabic minute track, with blued steel hands within canted brass bezel, the arched case with full-height glazed front door enclosing fine scroll carved and pierced apron beneath dial over silvered beat scale inscribed CHRONOMETER, the rear with circular glazed lift-out panel, on cavetto moulded skirt base with outswept block feet, 48cm (19ins) high; with original carved mahogany wall bracket with moulded platform over elaborate strapwork scroll pierced bracket support applied to a cavetto moulded back panel, the clock and wall bracket 95cm (37.5ins) high overall. Provenance: The property of a private collector, Hertfordshire; purchased at Bonhams, New Bond Street, sale of Fine Clocks 15th December 2009 (lot 60) for £2,880. Alexander Dalgety is recorded in Loomes, Brian Watchmakers & Clockmakers of the World, Volume 2 as working in Deptford circa 1847. Evidence in the backplate and the pendulum (in the form of a jewelled pallet applied to the rod) of the current lot would suggest that the movement was originally made with a rare form of detached detent pendulum escapement perhaps similar to that seen on a skeleton clock illustrated in Royer-Collard, F.B. SKELETON CLOCKS on page 29 (figure 2-16).
