Just wondering if anyone knows how many variations of the thermos carrier were made? I'm throwing out a wild guess on what I have pictured here...from right to left...64 pattern, late 64/early 82 pattern, and the easily recognizable 82 pattern. The middle one is the same construction as the 82 pattern but made of the earlier OD cotton material. It is also missing the eyelet that the 82 pattern carrier has.
