Throughout the years four additions were added and on June 26, 1968, Handy & Harman Refining Group, Inc. purchased the Attleboro Refining Company. In November 1973, Handy & Harman left 42 Union Street for a new facility located on Townsend Road in the “new” Attleboro Industrial Park. On November 29, 1976, Handy & Harman turned the 42 Union Street building over to the Chamber of Commerce of the Attleboro Area who acted as caretaker while the Attleboro Area Industrial Museum, Inc. attained non-profit status with the federal government. The building was in great disrepair when donated to the Museum so, for the first few years, the Board of Directors and Incorporators were concerned primarily with the rehabilitation of the building and grounds. The incorporators were J. Jerome Coogan, Emilio G. Gautieri Jr., George S. Gibb, Elizabeth Hartshorn Phillips, August H. Schaefer, and William H. Ward. The building was located in the jewelry manufacturing center of Attleboro when built in 1899.
