I am often asked: "I have an old pair of Peerless with serial #xyz, will a standard key work with it?" Is there a reference guide that can help you determine model #s just by serial #s? Also, is there a rule of thumb for determining whether an old American, Hiatts, Peerless, or S&W cuff uses a standard key? When did modern universal keys becom the standard? Thanks.
