Check the Hudson's Bay Company Archives (Internet search will give you their email address). There is also a Fur Trader's museum in Nebraska or someplace near there, who may have information on such coats. Pendleton Woolen Mills also produces blankets as with the Hudson's Bay Company or Whitney point blankets that were traded and made into coats used by trappers and Native American Indians. Jas. Townsend Company has patterns for making such coats.
