Help dating/identifying fur coat

[kate_bugs]

Hello, I was wondering if I could have some help dating this fur coat I just purchased, and maybe figuring out what type of fur it is? This is my first time posting here, if any more information I need to include or anything like that please let me know! Thanks so much xx

It looks a lot like muskrat, but I am not totally sure. It could be some other small mammal.
