Armstrong Brothers Tool Company was established in 1890. Early products were bicycle-related. In 1893 one of the brothers patented a tool holder that proved to be an immediate success, and that niche became the company's specialty for decades. Over 100 years later the company has diversified considerably. We note that for dating Armstrong catalogs, the company apparently moved from 317-357 and 368 N. Francisco Ave. to 5268 W. Armstrong Ave. in fall 1947.
