1L Labeflasche marked ESB 42

Nice 1 liter capacity canteen or Labeflasche in used condition. The canteen itself is nicely marked ESB 42 which indicates production by Eduard Sommerfeld, Berlin, the cup is a mismatch marked MN39 but this is the type as used on the 1L canteens! The canteen is in used condition with some minor flaws but all original parts are present. Nice original example!
