Notes: "The 4092 was K&Es first log log slide rule, introduced in the 1909 catalog and produced until 1921. The 4092 was succeeded in 1922 by the 4092-3, which added four more scales and a more useful scale arrangement. In 1925 a K scale was added, and the 4092-3 made its last appearance in a K&E catalog in 1938. This 4092-3 has a K scale, so it was made between 1925 and 1938. "
