content: MACHINERY RECORDS, 1910-1920, consist of mechanical drawings of machines used in piano keyboard production.  There is a series of drawings for each machine.  Most of the drawings are of very specialized machines designed for working with ivory, such as junking saws, planers, and laying machines (see p. 17).
