Spark plugs were invented in 1860 in France. Since then, many different styles and brands have been manufactured. Shown here are four complete and fragmented spark plugs from a vanished farmstead in Ottawa County. Archeologists from the Kansas Historical Society visited the site in 1993 during a highway survey project. One spark plug shows the brand name "Champion," which was founded in 1908. Another has the "AC" label, representing the AC Spark Plug trademark which first appeared in 1927.
