This is an injection-plastic airliner model kit.
The Boeing 707 prototype first flew in 1954 and the first order was placed by Pan American in 1955. In 1956 BOAC (British Overseas Airways Corporation) ordered 18 of the larger 707-420 'Intercontinental' version of the Boeing 707, powered by Rolls Royce Conway engines, instead of the usual Pratt and Whitney JT4A engines. To comply with British airworthiness requirements, a taller fin and rudder and a ventral fin were added. Known as the 707-436 in BAOC service, they started flying scheduled services in May 1960.
Completed model measures 323mm long with a 300mm width.
