It is complete, has its original instructions and original box. The box and instructions have only a very small amount of creasing and wear. The set itself has only one hairline crack, in one of the triangular pieces which hold the red jets onto either side of the craft. The jet still clips firmly into place though (bottom left of photo - the one you can see is actually the damaged one).
It contains 28 pieces (including some rare pieces) and 1 figure, and was originally released in 1987.
The two triangular pieces on either side rotate through 180 degrees so the red jets point either forwards or backwards. The front weapons are also hinged, and move approximately 100 degrees sideways. The box and instructions show three alternative designs.
