Len Peterson (1904–1981) began working at Adelaide jewellers S. Schlank & Co in 1919, and was closely associated with them until they closed in 1970. This is an edited version of his reminiscences, compiled between 1976 and 1980 for the Goldsmiths Guild of SA, giving an insight into the 20th-century Australian jewellery trade – its size, organisation, people, specialisations, products and techniques.
