Thanks everyone. I don't mind too much about what fur it does turn out to be. I got this stole for £1 at a car boot sale, and the thing i love most about it was the discovery that it was sold in a furrier just down the road from me that I never knew existed. I was asking my gran about it, and she remembered the woman who ran it, so that was quite nice. Thanks Carrie, for the keyword help, I’ll definitely use some of those words.
Unfortunately, I don't know any fur experts, so there isn’t really anyone I can ask. I suppose one of the reasons that I did ask for fur ID help on this one is that I sold a derry and toms one earlier in the year, and it was silkier (I asked about that one too, and you guys told me it was mink). This stole is smooth and silky but maybe not as good quality? I put that down to all animals having slightly different fur, but its entirely possible that this has been dyed to resemble mink. I just wish I could be sure.
