This is exactly the dialogue I wanted to prompt. Thank you for providing the pdf resource. I have been trying to find good color images of authenticated Luristan bronzes so I can compare the patina. The B&W images in the document you provided look very similar to the object in question, so color images would give us a reference point by which to compare.
Thanks, Ian!
Oh, and the seller had listed this as simply "bronze sculpture", so I don't think it was priced as it would be if they knew what it is intended to look like.
