According to the book Cobra! by Birch Matthews Bell made two of these Bu# 90061 & 90062. Flying test beds, NACA @ langly field kept one after Bell was done with them, Bell kept theirs for testing the wing for the X-2.
I too would presume they were cut up being that was the "norm" back then. Would be cool if one was still around
BTW, is that pic photo-chopped? cuz the exact same one in the book shows a man standing next to the RH wingroot. Just curious???
