This lever-type lock key arrived in the collections of the Kansas Historical Society with either no or lost provenience, its record of ownership. While this is disappointing it does not mean the key has lost all of its utility and value. It can still be used for teaching purposes as an example of an early historic artifacts in Kansas. The key consists of a bow (the portion which is gripped and turned) and a blade (which slides into a keyway, also called a key hole). The manufacturer added the numbers "358" to blade.
