This is an injection-plastic airliner model kit.
From the manufacturer:
The Bristol 175 Britannia was a British four-engine turboprop passenger plane, designed inthe late 1940s by the Bristol aero manufacturer. Series production began in the mid-1950s, and the first flight with paying passengers was at the beginning of 1957. The Bristol 175 Britannia was intended to be the flagship airliner of the leading British airline B.O.A.C., but several technical problems held back its development, limiting the production of the type to 86 units. Apart from B.O.A.C., planes of this type were used by other well-known air carriers such as Monarch and African Safari Airways, created in 1967, the principal bases of which were airports in Africa which had intensive charter flights from major European capitals at that time. Operation of the Bristol Britannia by Safari African Airlines lasted a relatively short while, until 1972, when its fleet was finally changed to jet aircraft exclusively.
