According to Loomes 'William Barnard was perhaps Newark's best-known clockmaker, probably because he was the most prolific.'
William Barnard was born in Newark about 1710 and was apprenticed for seven years, probably at the usual age of fourteen, not to a local clockmaker (Gascoignes), but to clockmaker Daniel Tantum, who at that time (1724) worked in Nottingham, a dozen or so miles to the west.
He was working in Newark between 1740 and 1785. This movement is numbered 1139. Another of his movements, n° 969, was dated 1769. An average output would be around 30 per year, so we can assume that this movement was made in 1774-5.
Movent runs but no pendulum or weight included.
The bell is a 20th-century replacement.
