Vintage Fur coat

I know this is real fur I’m assuming it’s beaver ? These are all vintage finds I was a house keeper & was gifted a lot of furs from a family who’s grandma passed I was told all of the coats are from the 60s. This coat is so extremely soft & so so so comfortable will keep you so warm & makes you feel like a million bucks honestly. I’m not a fur person but after owning these I see why people use to big on this stuff. There’s no size tags but I’m 5’4 135lbs & there’s still a lot of extra room
