This model is in 1/700 scale. It is part of a new range in this shop of Space focused equipment. It is a single sprue with two wires connecting the two seperate objects. The first object is an X-20 Dyna-Soar attached to a Titan III rocket. The second object is a seperate X-20 with gear down. Once the two wires are cut the models do not require any work to finish them.
According to Wikipedia: "The Boeing X-20 Dyna-Soar ("Dynamic Soarer") was a United States Air Force (USAF) program to develop a spaceplane that could be used for a variety of military missions, including reconnaissance, bombing, space rescue, satellite maintenance, and sabotage of enemy satellites. The program ran from 24 October 1957 to 10 December 1963, cost US$660 million ($5.08 billion today), and was cancelled just after spacecraft construction had begun."
