Large canteen marked WWL 42

Nice late war large 1L capacity canteen or “1L Labeflasche” in good used condition. The canteen itself is nicely marked WWL 42 which indicates production by Wilhelm Wiesenauer, Aluminiumwarenfabrik Ludwigsburg in 1942. WWL is an extremely rare to find maker and for me the second example I encountered! The canteen is in overall good condition without damages and comes in its original configuration with a black phenolic resin cup!
