Hi, Lovely piece of fur history here. It is muskrat fur however it looks a little bit older than the 60s. I believe based on the collar, sleeves, and piece of the lining I can see that the fur dates to sometime from the 40s to early 50s. The furrier is still in business today but is now partnered with another furrier. The business is still in New York but called Voziou-Davellin Furs.
