Hmm... if you bend it straight, it looks like it was feathered.
Thinking about this for a while, and quoting from myself...
I don't know the Metroliner engines/props but, if the prop control system is anything like a simple system, it may be that the prop blades will go to the feather posn after loss of oil pressure. Ergo, they might have moved to the feather posn after the crash.
Just a thought.
