German Esbit Metal Folding Army Stove - 1970's
A used, zinc plated steel folding stove to the West German Army.
This form of the model of stove was adopted in 1969, and has the NSN or Nato Stock Number to front (left side).
It burns alcoholic solid fuel blocks. None are present, and by the looks of the interior, it has been used in the past.
Maker marked on most surfaces to "Esbit", with Bunde Eseigentum or "Federal Property" to front.
It folds open and closed properly.
I believe its no longer issued. A similar model was also used in WW2.
