Shapleigh, who started in the hardware business in 1843,,in St. Louis, Missouri, was a successful businessman who, through the,years, was with various partners. In 1864, the famous Diamond Edge,trademark was established, and eventually the word “Diamond” was used,as part of other brand products. This box has the words: “Shapleigh’s,Diamond.” In 1918, the company incorporated under the name,Shapleigh Hardware Co.(void of any other partner’s name). The company,closed in the early 1960s.
