The 13in (32cm) vase, with an unusual turned-down ruyi mouth and a typical array of enamelled auspicious emblems and flowers to the imperial yellow ground, carries a calligraphic Qianlong (1735-95) four-character mark to the base.
The latter is thought by consultant Douglas Wright – who has given the vase a clean bill of health – to denote the early years of the reign of the fifth Qing emperor Jiaqing (1795-1820).
It is very similar in form and decoration to a vase with a red six-character Jiaqing mark sold by Christie’s Hong Kong as part of the Fonthill Collection in December 2010.
The base bears labels for the Dartington Hall Chinese Exhibition, 1965 and the collection of Sir John Saunders (1917-2002) who was chairman of HSBC from 1962-72. According to family history, the vase was acquired in 1982 from Ohio dealer Charles Gerhardt (1932-2015).
A successful sale would make the vase the first seven-figure lot sold in the UK regions for five years and the first ever sold in Scotland.
