London – A rare silver-mounted gold-koftgari steel repeating flintlock sporting gun from the personal armoury of Tipu Sultan sold for £312,750 at Bonhams Islamic and Indian Sale in London on Monday 25 October. Made by Sayyid Dawud in the Haidernagar workshop, it had been estimated at £250,000-350,000. The sale made a total of £1,900,000.

Bonhams Head of Islamic and Indian Art, Oliver White, said: "Tipu Sultan, often called the Tiger of Mysore, was a ferocious and tenacious warrior with a formidable personal armoury. This fascinating sporting gun bore the distinctive control mark of weapons made for Tipu's personal use. It was almost certainly picked up from the battlefield at Seringapatam and may possible even have been with the Sultan at the time of his death which added to its appeal for collectors."

Other highlights of the sale include:

• An Umayyad bronze censer in the form of a horse from the eastern Mediterranean, possibly Syria, 7th/ 8th century. The existence of incense burners is recorded very early in Islamic history and was almost certainly heavily influenced by their use in Byzantine liturgy. Though the influence of Byzantine art is visible in the present lot, the horse has been rendered in an altogether more stylised manner than examples from the Christian East, such as the Horses of Saint Mark in Venice. Sold for £125,250. (Estimate: £100,000-120,000).

• An extremely rare and fine example of the order of the Propitious Star of the Punjab (kaukab-i-iqbal-i-punjab), instituted by Maharaja Ranjit Singh, second class. Fascinated by the idea of European medals and orders, Ranjit Singh introduced three fixed awards of his own. The highest was for Princes; the second class, for 'relatives and brotherhood' of the Maharajah and the third for high dignitaries, colonels, and those providing honourable service. These were differentiated by the quality of the stones: respectively, diamonds, diamonds and emeralds, or emeralds only. The recipient of the Order in the sale is unknown but judging by its quality it was intended for presentation to members of the second rank - courtiers, sardars, governors of provinces, General officers, diplomats and envoys. Examples of these orders are very rare. Sold for £72,250. (Estimate: £60,000-80,000).

• A fine and unusual double-sided album page from the imperial Mughal library during the reign of the emperor Aurangzeb, with scenes from the life of the Sufi shaykh Majd al-din Baghdadi. From Herat, 16th century, with Deccani and Mughal additions of the second half of the 17th century. Sold for £69,000. (Estimate: £12,000-18,000).
