This tool can date any Kemble piano made between 1930 and 2009 when they were bought out by Yamaha. If your Kemble serial number contains any letters then it will not work and is most likely made after 2009. The serial number on a Kemble piano is found on the top of the frame. Lift the top lid and it should be visible, normally to the right hand side of the piano frame.
