Does the lining have an elasticized opening above the wrist? And are those sleeves bell-shaped?
I find fur coats can be hard to date, and I'm not an expert in identifying them. But I think this is probably 1950s (earlier rather than later, I think). I've had some from the '40s that look similar in style, but the lining looks a tad newer than that. Wish I could get my hands on it "in person."
I hope somebody more knowledgeable than I am comes along.
