Strictly a mockup.
This airplane never flew. Rivets and Fasteners, not Milspec standard. Sheetmetal of poor finish and quality. Pitot Tube not aligned properly, landing nose wheel door not correct. Landing gear too short, wrong size tires and wheels. Munitions racks would inhibit deflection of control surfaces. Cockpit using stereo-equipment to simulate avionics. Wrong Hud, Ejection seat and upfront controls. Insignia painted incorrectly.
Overall, very good mockup, but built with some aviation parts from other aircraft and numerous hand crafted panels. Someone's labor of love now on display.
