The Cobham Pottery also known as Surrey Pottery Ltd was established by Doulgas Zadek in c1947 and operated until 1956. The products of this pottery are generally small scale earthenware vessels with many "tinies" being produced for the 1953 Coronation. Benny Sirota of Troika fame worked there from 1953 learning his trade.
Douglas Zadek was born in 1913 in London. He studied at the Bauhaus in the early 1930's and on returning to England he worked for Muriel Bell at the Malvern Pottery and from 1936 with Bernard Leach in St Ives, replacing Harry and May Davis as his assistant. He died in 1995.
Most items that I have seen are small simple shapes with slip decoration and some incised decoration. Impressed marks are clear on the underside. Commonly "Cobham" and some with a circular DZ mark/monogram.
Strangely mainly jugs also small dishes and vases. A multitude of tiny commemorative items produced for Queen Elizabeth II coronation in 1953.
