This interesting example has a fragment of a label...
Llewellynn Jewitt, History of Ceramic Art, 1874.

The Jewitt quote specifically refers to a brown stoneware loving cup (illustrated direction). Formerly in the collection of Derbyshire potter John Brameld but now unlocated, the cup bore an incomplete label saying that it had been made at his Swinton factory. The nearly identical example in the Noël Hume collection, like the Brameld cup is dated 1759. There can be little doubt that this is a twin to the Brameld cup and therefore a defining example of Swinton brown stoneware, of which little is yet known.
