Belden, R. A. & Co.
R. A. Belden & Company (New Haven & Danbury, CT) - This company was started ca. 1864 by inventor Russel A. Belden, and moved to Danbury in 1871. Leading Businessmen of Fairfield County, and a Review of the Principal Cities, published in 1887 notes that the company manufactures "the famous Guthrie and Climax wrenches." Please note that we do find indications of a Guthrie Wrench Manufacturing Company in Danbury in 1885, but nothing more than a seemingly passing note, and only in 1885.
