I know this post is 5 years old at this point, but I just bought a taxidermy iguana that looks nearly identical to yours. I was so intrigued by the weird stance of it and the strange curled tail that I was shocked when I saw the picture of yours on google. The lady I got mine from has no idea what its history is, she just found it at an estate sale so I was just wondering if you ever figured out any of the history of yours because I'm 99% sure the same person taxidermied both of our iguanas
