Indeed a beauty. I've bought it recently and althought I do not collect hunting hangers, it was love at first sight. 
And as we know, love could be costly nowadays... but I just couldn't help myself. 
 
Thank you very much! Very helpfull Jim, as always.
What about the marquese crown? Any family in particular from that area, Jim?
Rock or bezant, I do not know, but that animal is definetly a stork, as in heraldy cranes and heirons have shorter beaks.
