Telegraph Apparatus Company

Semi-automatic in kit form! In the mid-30's the Telegraph Apparatus Company of Chicago advertised their "Speed Key" offering either a heavy chrome or colored lacquer base. The pendulum was mounted through a 1 1/4 X 3 3/4 in. rectangular bridge. During World War II the Lionel Company produced these keys for the armed services. Here is the Chrome model that needs a good cleaning but is in very good shape!
