This is a resin-cast aircraft kit.
The Aero Commander 520 is a reciprocating-engine twin light aircraft that flew for the first time in 1951. The U.S. military adopted it and called it the U-4 (Air Force) and U-9 (Army). From 1956 to 1960, a U-4 was used as the U.S. President's special aircraft, Air Force One, and the Belgian Air Force used it for the transport of royalty from 1961 to 1973. This resin kit includes a vacuum canopy and decals for three versions (U.S. Army, U.S. Air Force, and one civilian machine).
