This vintage coat was made in the 1930s from Hudson’s Bay Company point blankets. It is a classic double breasted mackinaw cut. At some point, the coat was fully lined, but where it is coming away, you can see the taped seams and hanger loop which give away the original unlined construction, which was typical on blanket mackinaws of the era.
