Presentation spyglass that led to the capture of Spanish slave ship "Vengador"

A telescoping spyglass presented to Sir Llewelyn Turner by Admiral Lord Clarence Edward Paget. The outer tube of the spyglass is made of mahogany and has brass fittings holding glass lenses. A presentation plaque is attached to the side of the outer tube by four small screws. The plaque reads “PRESENTED BY / Admiral Clarence Paget, G. C. B. / TO HIS FRIEND / SIR LLEWELYN TURNER / By means of this Night glass, / the Spanish Slaver “Vengador” with 500 slaves, / was kept in sight during an entire night (A.D. 1838) / and Captured after a chase of Seventeen hours, / which led to the Capture of her Consort.” A thinner tube made of brass slides into the wooden outer tube. A glass lens is fitted into the end. Etched on the inner brass tube of the spy glass near the lens is “Watkins & Hill / Charing Cross London / Night."
