The USS Hartford Helm

This is the Hartford Helm. A helm is a tiller or wheel and any associated equipment for steering a ship or boat. Here is a description of the USS Hartford from a Wikipedia article:

The USS Hartford, a sloop-of-war, steamer, was the first ship of the United States Navy named for Hartford, the capital of Connecticut. Hartford served in several prominent campaigns in the American Civil War as the flagship of David G. Farragut, most notably the Battle of Mobile Bay in 1864. She survived until 1956, when she sank awaiting restoration at Norfolk, Virginia.

This helm was salvaged from the ship and is on exhibit in the U.S. Naval Academy Museum in Annapolis, Maryland.
