Vintage coat with faux fur collar

ok, I have found no tags in this coat at all. it's a cool coat and in nice shape. Besides, a few stitches need to be repaired, and it needs a good cleaning. the faux fur collar has been safety pinned on all the way around. has the belt and all and an impressive red inside! it does has a slight pink stain from the red liner inside but cld be cleaned? I can wear between a large and xl and it fits me. so I assume it's that size.
