A fine mid 19th century floorstanding mahogany regulator with mercury jar pendulum Attenborough, 84 Brompton Road, London. Further signed 'THIS CLOCK SHEWS GREENWICH MEAN TIME' (sic) The case with pierced dependent cresting below the dial revealed through the full length curved-top glazed door with two locks (keys present) over a recessed panel base, the 11.5 inch silvered dial signed for Attenborough with sight ring and minute track framing the large subsidiaries for running seconds and Roman hours, all with blued steel hands, the substantial plates set on a very heavy brass base via three substantial L-shaped brackets and united by five heavy tapering pillars screwed to the frontplate, with Harrison's maintaining power, wheels of six crossings, high count pinions and jewelled pallets to the deadbeat escapement, the steel crutch with fine-screw beat adjustment to the mercury jar pendulum with further regulation screw adjsutment, reading against an engraved silvered beat scale, the whole movement mounted on a massive cast iron bracket secured to the backboard of the case, with brass weight and fancy pulley of six-crossings. 1.95m (6ft 4.5ins) high Footnotes: The name 'Attenborough' and the number '84' have both been engraved over a hammered up area (as can be seen from the back of the dial), the Brompton Road and GMT proclamation appear to be original. It would be sensible to assume, therefore, that Attenborough bought this regulator for his own shop or workshop from one of his retiring neighbours on the Brompton Road. Two Attenboroughs are known to have traded in London, James in 1857 and George in 1869, George took his son into partnership in 1875.
