Lost/abandoned, does anyone recognise her?

We have a very sad and terrified adult cat (probably female) we suspect has either been lost or abandoned, does anyone recognize this cat? If we cannot find an owner we will have to bring her in for adoption as clearly she will not last the winter and her coat will matt causing pain and infection. Any help appreciated October 2017: Fluffy has settled in well here, a gentle loving lady, we are sure she will find a loving home once she is at Woodland Nook
