Description
 
A volvelle for "hand semaphone" or otherwise known as flag semaphone, which is a telegraphy system used to convey information across distances by means of visual signals. While the system can be used with bare or gloved hands, generally speaking flags or flashlights (at night) are used. Produced for the US Naval Training Device Center by the Huntington Specialties Company, this two side volvelle has instructions both for signaling and receiving hand semaphone. As one turns the wheel the the sailors 'arms' reflect the proper signal for each letter in the alphabet. For some reason they are 29 letters on each side as three letters (D, R, and L) are repeated. Measures 4 1/4" x 4"..
