1 liter Gebirgsjäger Labeflasche marked CFL38

A scarcely encountered Gebirgsjäger specific 1 liter capacity canteen or Labeflasche. These canteens where fitted with a carabiner hook on the back so that it could be worn on the carrying sling but also on the breadbag. The canteen is nicely marked CFL38 indicating production by Carl Feldhaus Aluminium-und Metallwerke, Lüdenscheid. These 1 liter Gebirgsjäger Labeflaschen with both the harness and the hook are very hard to find!
