caption_attribution_description: English: 5.25-inch BL CA/AA QF Gun A WW2 army version of an originally naval weapon, a dual purpose coast and AA gun. It was envisaged as an interim medium gun pending the design of a one of 6 inches. In practice the post war installation of these and training shoots proceeded up to the abandonment of coast artillery in 1956. Accordingly this type were actually the last coastal guns installed. The four guns here are believed to be the only remaining ones still in existence. Princess Anne's Battery, Gibraltar.
