St. Louis Vise & Artesian Well Co.
St. Louis, MO (The Railroad, Telegraph, Electric and Steamship Builders' Buyers' Guide, 1897)
We believe this company began in 1874 as the St. Louis Vise & Tool Works. The State Journal (Jefferson City, MO) of 4/17/1874 carries a notice that the company has been formed to manufacture blacksmith and machinist' tools. Throughout the late 1800's, we find many notices of the company demonstrating their well drilling tools and equipment.
Google Books searches indicate the company went by both names. They are located at the same address throughout the late 1800s. The company fades away by the late 1890s.
