Maker is the Knapp-Monarch Company, St. Louis, Missouri, founded in 1925 as A.S. Knapp and Company, not as a manufacturer, but to sell products. The company merged with manufacturer Monarch Company of Webster City, Iowa, in 1928. A large portion of Knapp-Monarch’s business was the manufacturing of products for private brands. In 1969 the company was acquired by the Hoover Company.
