1. Napoleonic prisoner-of-war ship model
La Bellone was a 32-gun frigate built in St Malo in 1778. Captured at the Battle of Tory Island, off the north-west coast of County Donegal, in 1798 she was brought to Plymouth and re-named HMS Proserpine but broken up a couple of years later in 1806.
This bone model comes for sale as part of a Devon collection of Napoleonic prisoner-of-war work at Charterhouse Auctions in Sherborne on August 3-4. It is estimated at £3000-5000.
2. Charles II lantern clock
Made in the early 1660s, this Charles II lantern clock, above, with balance wheel, verge escapement and alarm mechanism is signed to the dial Thomas Knifton at the Cross Keys in Lothbury, Londini. It has an estimate of £3000-5000 at Hutchinson Scott in Skipton, North Yorkshire, on August 2-4.
The prolific Knifton (c.1614-67), was one of the close-knit group of clockmakers working in the parish of St Margaret’s, Lothbury, in the years before the Great Fire. He served his apprenticeship under the early maker William Selwood and like him was a Parliamentarian – perhaps the reason he did not become a member of the Clockmakers’ Company.
