This fine quality British Admiralty instrument was recently fully polished and cleaned, and is in excellent functioning condition. Dated 1942, and with the Broad Arrow admiralty mark, they were undoubtedly put into World War II service. The metal tripod stand is polished as well, and is a very adaptable way to show and use this instrument in a home setting, whereas onboard a ship they would have been stationary mounted to an observation platform rail. A top quality optical instrument of the 20th Century.
