This paper model is a V-1 Flying Bomb (aka Buzz Bomb or Doodlebug), an early pulse-jet-powered predecessor of the cruise missile, the papercraft was created by Ralph Currell, the finished model by Horst Brinkmann. The scale is in 1:32, and the length of the completed model is over 10 inches and wing span over 6 inches.
The V-1 was developed at Peenemünde Army Research Centre by the German Luftwaffe during the Second World War. During initial development it was known by the codename "Cherry Stone". The first of the so-called Vergeltungswaffen series designed for terror bombing of London, the V-1 was fired from launch sites along the French and Dutch coasts. The first V-1 was launched at London on 13 June 1944, one week after the successful Allied landing in Europe. At its peak, more than one hundred V-1s a day were fired at south-east England, 9,521 in total, decreasing in number as sites were overrun until October 1944, when the last V-1 site in range of Britain was overrun by Allied forces. This caused the remaining V-1s to be directed at the port of Antwerp and other targets in Belgium, with 2,448 V-1s being launched. The attacks stopped when the last site was overrun on 29 March 1945.
The British operated an arrangement of defences to intercept the bombs before they reached their targets as part of Operation Crossbow, while the launch sites and underground V-1 storage depots were targets of strategic bombing. [Source: wikipedia]
