Hi all, I would really appreciate if someone could help me on my little problem. I was going through some clutter in the attic and I came across my Grandma's very old but very beautiful fur coat. Now I've had a real good scan of it, it IS definitely real fur, but from what animal I can't be completely sure. I'm strongly presuming Mink. My real question is when I was looking through the entire jacket I came across a label under the left breast that says 'JR5807S' in very old printing. other than the size label, there are NO other labels to prove its authenticity (other than the feel of it, and the underlining).. I am desperate to know more about this coat! Please please help if you can.
