Can't Find My Derailleur Hanger
Yours rotated looks like 

Best I could find is http://wheelsmfg.com/derailleur-hanger-6.html 
which is "similar" but the mount holes look too large, the duck bill is way wrong, and the curve is there but wrong.

The holes might kill it, but its possible the other parts aren't critical.  



Don't bother with the emergency hangers for long term use - they don't last long and they don't work well.
