A three-day antiques sale which begins on Wednesday features everything from Percy Kelly artworks to a Chinese silver tea service, a 17th century dresser, and a Russian emerald and diamond bracelet.

But it is the sale’s clocks that are likely to fetch some of the highest prices.

By far the most valuable item in the sale, from Cockermouth auctioneers Mitchells, is a rare longcase clock by Edward Harriman of Workington.

It dates from around 1765, has an oak and mahogany case, and is likely to sell for £7,000 to £10,000.

A Victorian gothic walnut clock and an early 19th century French Boulle mantel clock, made by Margueritte of Paris, are both expected to make between £1,800 and £2,200.

A George III mantel clock by Weeks of Piccadilly has an estimate of £500 to £800.

The sale also includes a large furniture section, with pieces from every era.

A pair of satinwood hand-painted cabinets are likely to sell for between £3,000 to £4,000, a late 19th century Vernis Martin ormolu mounted cabinet is valued at £2,000 to £3,000, and a Victorian walnut piano front Davenport desk could fetch £1,200 to £1,800.

The 17th century English low dresser and a Gordon Russell sideboard could both make £800 to £1,200, and a good Victorian walnut credenza with Sevres-style porcelain plaques could sell for £1,000 to £1,500.

A pair of unusual leather bedside chests of drawers modelled as trunks, a large Victorian oak serving table and a George III style mahogany serpentine chest of drawers are all estimated at £500 to £800.

A Chinese Chippendale inspired two seater settee should sell for £400 to £600 and an Edwardian satinwood side cabinet with a series of drawers, cupboards and apertures is valued at £350 to £450.

Particularly eye-catching and valuable lots among the ceramics are a large Moorcroft koi carp vase by Sally Tuffin valued at £1,800 to £2,000 and a pair of William Moorcroft Moonlit Blue vases from around 1928, valued at £800 to £1,200.

The jewellery section features rings and wristwatches which will fetch prices in the thousands.

A rare Russian emerald and diamond bracelet among them is expected to sell for between £3,000 to £5,000.

And in the silver section there is a Chinese silver tea service dating from 1890, which could make £600 to £800 and a pair of George III-style silver candlesticks made in 1972, with an estimate of £250 to £350. A Josef Lorenzi painted bronze figure should make £150 to £200.

There are several Percy Kelly works in the art section, including a charcoal Above Loweswater valued at £2,000 to £3,000.

A pair of oil paintings by H Aiken from 1791, featuring equestrian scenes, could sell for £700 to £1,000.

Other artists featured in the sale include William Heaton Cooper, Alfred Wainwright, Len Roope, Audrey Johnson and Edward Horace.
