Sopwith 5F.1 Dolphin at the WWI Hall, Grahame White Factory, RAF Museum, Hendon, 13 September 2015. Unusually, the Dolphin had backward staggered wings to improve pilot visibilty. It was the first 4 gun fighter designed for high altitude interception. However, it was more successful as a low altitude ground attack aircraft!
