I found a pitcher at my mothers house.It has a glass liner and looks to be metal.Reading here has convinced me that it is a first of a Landers Frary & Clark thermos.The bottom unscrews to let the glass come out.There are dates on the bottom of pat. type 1914-1917.This one was made in New Britian Conn.USA. The date is June 13,1916. It is not in to bad of shape some of the metal has chipped off the handle but I so love the pitcher.
