A number of these models were made for Boeing, Pratt & Whitney, and
the Air Force Research Laboratory, with each buyer affixing its own nameplate. It's in 1/15 scale, with a fuselage length
of 20 inches. Nameplate reads "X-51 - USAF/DARPA - Hydrocarbon Scramjet Powered Hypersonic Waverider Flight Demonstration
Vehicle." The X-51A will have two components, the ATACMS booster and the scramjet-powered hypersonic waverider,
and the model displays them separated. John Tam was instrumental in helping me obtain this.
