Records, 1869-1967, of John Swire & Sons Ltd, comprising the bulk of known surviving material stored in the London Office, covering the development of the firm from about 1870 to 1947, and including series of correspondence coming in and out of the London Office; legal material including original deeds and leases; accounts; organisation papers; and photographs. The importance of the collection lies in the comprehensiveness of the nineteenth and twentieth century correspondence in illustrating the development of the firm and its subsidiaries from the London side where policies were decided, and from the Eastern side where they were implemented. It also gives a good picture of leading figures and firms involved in the Far Eastern trade at that time such as Jardine, Matheson & Company, the China Merchants Company and Holt's, and reveals aspects of Chinese trade and British business philosophy at the end of the Victorian era.
