Wehrmacht M31 Canteen and Cup (Feldflasche 31 und Trinkbecher). The standard issue M31 canteen was introduced on 23 March 1931. The aluminum canteen and leather straps are in good condition with normal traces of usage. The felt cover is in good used condition. The canteen is complete with its black aluminum cup. The canteen is maker marked and dated 'MN41', the aluminum cap however is maker marked and dated 'SMMS39'.
