Authentic Misericorde?

[Athene]

Hello friends! Please take a look at these pictures. My grandfather has had the item for many years. As the story goes, he bought it among a pile of junk at a flea market. Now, I'm not even certain that I know what it is and I really don't know if its the real deal or not.

May I have your opinion?

Thanks guys! :)
