Excellent textbook M31 canteen in unissued, mint condition. The canteen and all its parts are nicely marked SMM 42 which indicates production by Süddeutsche Metallwarenfabrik, Mussbach in 1942. Rare to encounter a 1942 produced M31 pattern canteen in unissued condition. Textbook fully matching and unissued unissued M31 example which is a must have for every canteen collector!
