The fonds consists primarily of Thomas Brayshaw’s fishing diaries (1932-1964) and correspondence, manuscripts, and subject files (1907-1967). This is largely reflective of Brayshaw’s work and related interests. The fonds also contains a collection of documents and research related to the Brayshaw family, containing genealogical research, and family photographs, personal records and artefacts. This includes some personal records of Thomas Brayshaw, notably war service records, and some photographs and fishing flies related to his work and interests.
