Much of it came from Viscount and Viscountess Bledisloe of Lydney Park, but three pieces of Chelsea decorated by Jefferyes Hammett O'Neale came from another family collection.
They included this 5½in (14cm) octagonal saucer, c.1752-54, painted with a rendition of Leda and the Swan.
Mythological scenes by the artist, who later worked at Worcester, are rare (animal subjects based around Aesop's Fables were his stock-in-trade) and this saucer was in perfect condition, with only slight losses to the chocolate brown enamel rim to count against it.
With an estimate of £3000-4000 at the sale on September 1, it attracted a host of UK and US bidders and ultimately sold to a UK bidder on the telephone at £16,000 plus 17.5% premium. Only larger pieces by Hammett O'Neale have made more.
