This sanguine (red chalk) drawing of horses’ heads by the Dutch artist Paulus Potter (1625-54) carries an estimate of £3000-5000 at Lots Road Auctions in Chelsea on October 20.

Potter, a precocious artist whose early works were painted as a teenager, was a pioneer in landscape painting with animals – a genre that was hugely popular in Holland from the middle of the 17th century.

The 5 x 3in (13 x 8cm) drawing comes with a long provenance. Owned by the Brussels artist Van Parijs (fl.1789-1839) and stamped VP n. 679 verso, it was later in the collection of Sir John and Lady Witt.

A watercolour and crayon study for one of Graham Sutherland’s best-known oils comes up for auction at an online sale of Modern and Contemporary art sale closing on October 27.

Abigail Molenaar, from Halls of Shrewsbury, said: “When we were shown this sketch we thought it looked like a preparatory study for the 1939 Gorse on a Sea Wall (now in the Ulster Museum) piece which established Sutherland’s reputation. All the essential elements are there. It’s only the composition and execution of the central forms that are different.”

Confirmed as an autograph Sutherland work, the estimate for Sea Wall II is £2000-4000.

This late 18th or early 19th century enamelled and parcel gilt huqqa from Lucknow is one of a number of pieces of Indian art from the Jourdan-Barry collection to be offered by Chiswick Auctions on as part of an Islamic & Indian Art sale on October 25. It is estimated at £2000-3000.

Marseille collector Pierre Jourdan-Barry, who died in 2016, formed collections in diverse areas entering the market of Indian decorative arts in the 1980s. He could be a strong bidder in the saleroom and had bought this piece at Christie’s in 2011 for £15,000.

The British and Continental Pictures sale at Olympia Auctions on October 23 includes more than 330 oils, watercolours, drawings and prints from the 17th-20th century, catalogued by Harry Moore-Gwyn.

This 9 x 8in (23 x 19cm) oil and gouache on panel by the Hon Roger Rollo (1777- 1847) depicts the Eglinton Tournament– the indulgent celebration of mock pageantry and chivalry held at Eglinton Castle in 1839.

As detailed in an extensive inscription on the back, his painting includes a depiction of Napoleon III and Lord Eglington himself (see detail left)

Rollo, second son of the 7th Lord Rollo, was an officer in the artillery and later in life the customs collector for the port of Ayr. A keen amateur artist, he was among the tournament’s most important attendees that were invited to spectate “on the pavilion erected for the Queen of Beauty”.

Estimate £3000-4000.

The Who’s Pete Townshend once said of bass player John Entwistle (1944-2002) that his “only real addiction was Harrods”. Among his many purchases from the Knightsbridge store was this Scottish parcel-gilt silver model of a three-masted galleon made by Brook and Son in Edinburgh in 1912.

Acquired for his Stow-on-the- Wold home, Quarwood, in the 1970s, when The Who were at the height of their fame (and Harrods had a substantial antiques department), it has stayed in the Entwistle family since he died in 2002.

It now features in the Fine Silver and Objects of Vertu auction at Woolley & Wallis in Salisbury on October 29 where it carries a pre-sale estimate of £4000-6000.
