Note: William Allam appears to have had some influences from the more well known makers during the 18th century such as Mudge & Dutton and also Vulliamy. The hands and spandrels are typical of work by Mudge & Dutton. The use of a square dial at this late period is also a style used by Vulliamy. The clock also features two original brass covered weights, one larger than the other and a heavy pendulum bob with calibrated rating nut.
William Allam was Free of the Clockmakers Company in 1743. Working alone at the beginning of his career he then joined in partnership with Clements in 1763 and worked until 1795.
