If you have an Emperor clock, you may enjoy these scans from two of their catalogs (ca. 1973). Emperor provided "do-it-yourselfers" with clock kits, from which they could build their own clocks for considerably less than buying a completed clock at the time. I have seen many of these clocks, so I expect they must have been popular. The Emperor Clock Company built clock cases in Fairhope, Alabama, installing German clock mechanisms, made mostly by Jauch and Hermle.
