This file was set up by Ray Chapman of the Bunker Hill Company. He gathered material from various files in the company offices into one chronologically arranged group covering the years 1885-1981. Since it would be very difficult and time consuming to return items to their original location Chapman's arrangement was retained. Included are court documents, early correspondence to and from Stanly Easton, some of which predates his employment as manager at Bunker Hill, reports of Pinkerton and Thiel operatives during the years 1905-1907, newspapers and newspaper clippings, magazine, reprints of journal articles, brochures and small pamphlets, and company newsletters.
