Moms fur coat became my fur coat

Very heavy I do believe it's vintage my mother has had it for years .I'm thinking 1950s or earlier . When I look up the label online Isaiah Napoli I get men's clothing . So I'm not sure if it's a man's for coat or a woman's fur coat .maybe it belonged to my dad or maybe that brand when they first started out their company did women and men's fur coats . Not sure what type of fur it is would love to find out the history on it thanks
