I just bought a Schott jacket from a discount store  labeled "parka, extreme cold weather, contract no. 345G, Stock no. N3-B-2238" which I love.  It is black nylon  with a black faux fur lined attached hood.  There is an internal zipper that appears to be for a lining and another around the hood, for perhaps a trim, but they did not come with it.  Could you tell me about this jacket, and whether or not a lining is supposed to be part of it, and where I could get one if possible..  It is warm without a liner, but I thought I might use it if I travel north.  Thanks
