This is the infamous Gunfighter probably right before her crash at Offut AFB when she was caught by a gust of wind. Reg Urschler and other USAF volunteers restored her again with almost a new airframe at Offut. This was allowed because Reg was the commanding general of the base at the time.
I believe this is Gunfighter before her crash. After the crash Reg restored her and it now belongs to the CAF and now is in different colors ... but still named Gunfighter
This one should have been finished off long ago. Ryan is right, it is N5428V #1, 44-73264. The new GUNFIGHTER II is 44-73273 N5428V #2, which was ex N34DD and N200DD.
