This is a die-cast metal model of a 747-400F from MASkargo. It is part of International Airport series which includes a cardboard section of runway along with a special clear plastic stand that positions the model in a landing or take off position, making the visual effect quite dramatic (as can be seen from the photos).
The model's fuselage is made of die cast metal and the wings, tail and engine are plastic. The landing gear can be position as extended or it can be taken off and the doors put in place to give the appearance that the landing gear is retracted.
