Just from looking at the label, I do not believe that this is 20s but rather 50s 60s. You might want to add photos that show off the construction a bit more... collar, how the shoulders meet the body of the coat, which will tell better the era.
What fur is hard to tell from your photos. You might want to add some close up photos of the fur, straight on and with a hand pushing the fur back so one can see the guard hairs and undercoat.
