Hawker Duiker, Woodcock, Danecock and Heron

The Hawker Duiker was an unsuccessful design for a reconnaissance aircraft that was noteworthy mainly for being one of the first two types of aircraft to carry the Hawker name.
The Hawker Woodcock was the first aircraft carrying the Hawker name to enter service with the RAF, and was a short-lived fighter aircraft that was one of the first generation of aircraft designed after the First World War.
The Hawker Danecock was a version of the Woodcock II fighter designed for Denmark, and produced under license there as the L.B.II Dankok
The Hawker Heron was an experimental metal version of the wooden Woodcock II fighter, designed by Sydney Camm early in his career with Hawker.
