The missile would be launched with a push of the tab located on the side of the mechanism. There are three variations concerning the die and mold of the flat car body, none of which are any rarer than the others. This car was produced from 1959 to 1963, and was equipped with AAR trucks and disc couplers. The missile has been reproduced.
