Vintage Mouton Fur Coat

Does anybody have any special knowledge about Vintage Mouton Fur Coats from the 1940s or on Mouton Fur in general?  I found one at the consignment store I go to and am only considering breaking my Closet Shopping Challenge because its in pristine condition, its vintage, its Mouton, its gorgeous and its only $65 (as opposed to the $300 it could get on ebay).
