Not more authentic. Wool collar is a Navy thing. I know some guys that had it put in, but most do not. As far as the liners, i havn't seen any fur liners inside the main part of the jacket. The "3m Thinsulate liner" is standard and is what I have, and I don't wear it unless its down near freezing because its too warm otherwise.
Do get the fur liner in the pockets. Its awesome and really helps keep your hands warm.
