These papers are the surviving records of the Musical Instrument Factory (MIF) 1893-1972.
The factory began making and repairing instruments for Salvation Army bands in 1889, and continued until the lease was transferred to Boosey and Hawkes Ltd in 1972.
No original order is evident, so the arrangement represents a logical grouping of the factory registers, catalogues and other administrative papers.
The arrangement of the records is as follows:
MIF 1: Administrative papers, 1893-1972
MIF 2: Registers, 1925-1972
MIF 3: Catalogues
MIF 4: Photographs
