By the hinge line, do you mean the wing fold? The wing fold is between the flap and the aileron, the wing tip jettison was further out, leaving a stub aileron.
Funny thing, I've never seen The Fighter Collection's Bearcat with her wings folded in 40 years (yes, she joined Stephen Grey's collection 40 years ago!) yet the second aircraft they operated for a short while certainly sat on Duxford's flight line with her hands up.
