Quiet Street Antiques of Bath has dated this piece to the 18th Century.
Interestingly there is a paper label to the back, (see image) which appears to indicate that this clock was retailed by J.Bowles of Dunstable ~ just 9 miles distant. Full working order.

Research has shown that a notice appeared in the Northampton Mercury of 30 November 1793 that William Emmerton, Clockmaker, had recently taken over the business of the “late Mr.Baker” in Woburn. This attractive wall clock can therefore be dated c1790 and certainly no later than 1793.
