How Old is my Everett Piano?

In 1883 that a musical instrument retailer, John Church Company, started producing small quantities of uprights and grand pianos under the name of Everett.

In 1973 Everett was sold to the Yamaha Corporation. They modernized the South Haven plant to produce both Everett and Yamaha upright pianos. Production at the Everett factory ceased in 1986, when Yamaha moved to U.S. piano plant to Georgia. The Everett name was licensed to the Baldwin factory until 1989. Since 1995, Wrightwood Enterprises Inc., has used the Everett name, and Dongbei Piano Company in China now makes their pianos.
