Artificial collection of material largely collected by John Findlay, including papers formerly in the possession of Mason's nephew Martyn Smith, with additional papers acquired from other, often unknown, sources. Papers consist of correspondence relating to Mason's career and business interests, legal records including property deeds, deeds of foundation of Sir Josiah Mason's Orphanage and Almshouses and papers relating to the terms of Josiah Mason's will, copies of records relating to Mason's family history, and ephemera relating to Mason's life and the arrangements for his funeral. There is also a file containing correspondence, ephemera and photographs relating to the orphanage which largely dates from the 1920s and 1930s but includes press cuttings relating to the demolition of the orphanage building in 1964.
The papers gathered by John Findlay in the early 1990s largely relate to Mason's family history and it seems that he used these and the correspondence and legal papers formerly belonging to Martyn Smith to carry out research on Mason's life, career, and philanthropic activities in Birmingham. As John Findlay was chairman of the Old Masonians Association, for ex-pupils of Sir Josiah Mason's Orphanage at Erdington at the time he was gathering these materials, it is likely that he was carrying out research as part of this role in order to provide information to members of the association.
