Sets of Drawing Instruments -- Flat Cases

Flat Cases

A Eugene Dietzgen Company set of drawing instruments.

While retailers often called this style of case a "pocket case," we have chosen the name "flat case" to avoid confusion with the earlier form of vertical pocket case shown on another page. Flat cases were usually fastened with a sliding pin known as a "bar-lock." They were sold most widely in the 20th century by firms such as Keuffel & Esser.
