This sextant has a frame of blackened brass. The silvered scale is graduated
every degree from -5o to +130o and read by ivory micrometer with electric light to 10 seconds of arc. The batteries for the light are in the handle of the instrument. Hughes was making micrometer sextants by the early 1930s.
Steven Memoli bought this sextant in Cardiff, Wales, in 1944. Memoli spent the war years transporting troops from the U.S. to Europe and North Africa; he also participated in the Normandy invasion. Several years after the end of the war, having been prodded by the U.S. Circuit Court, the Department of Defense granted veteran’s status to Memoli and other
merchant seamen of his ilk.
