Although this collection contains records from 1918-1989, the bulk of the records
range only from 1949-1989. Amongst this collection is a series of annual reports
for Twin-Disc. These annual reports are from 1949, 1951, 1953-1955, and 1964-1989. A
photocopy of the company’s original articles of association with the State of
Wisconsin from 1919 is also included in this collection. Two employee manuals and an
interview with Vice President of Finance Robert T. Howell are also included.
Research conducted by Twin-Disc has been broken up into four sections and discussed
more fully in the Arrangement section of this finding aid. Newspaper clippings from
the Racine Journal Times about Twin-Disc are also
included.
The clippings span 1971-1974 and 1978-1981. Issues of Production Road, Twin-Disc's corporate magazine, are included but are
incomplete, containing complete collections for volumes 34-40, but scattered issues
from volumes 31, 32, 33, and 41. In whole, there are issues from 1962-1963, and
1970-1981, but is incomplete.
The largest portion of the collection consists of numerous service manuals for
Twin-Disc machinery assembly and repair. For more about these service manuals, see
Arrangement.
