WW2 German Army Field Thermos Flask

Original WW2 German Army field thermos flask. Most often associated with the Gebirgsjager troops. Tin has its original dark green finish with the typical looped lock as seen on many German produced tins. The hook that holds the latch appears to have been sheered slightly, possibly to allow easier access. No stamps appear present. Some very small holes present in the groove around the middle of the tin. Thermos inside the tin in good clean condition. A rarely found piece of field equipment.
