Not sure about this one...came from a private British museum here in the States...since there are so many variations and copies out there I need a little help.

This is a copy as it doesn't match known examples.  The attached photos show two examples the first one some collectors had issues with initially due to the lack of a yellow eye but they are supposedly both genuine.  

 

 

I see what you mean...but I've searched the web and can't find another (even a repro) that looks like this one.

The originals always seem to have far better detail and materials used IMO.

Cheers
