Wehrmacht M31 Canteen and Cup (Feldflasche 31 und Trinkbecher). The standard issue M31 canteen was introduced on 23 March 1931. The aluminum canteen and black leather straps are all in overall good used condition with normal age and usage toning. The canteen is complete with its original felt cover in good used condition. The canteen-cup, feld cover and leather straps are all nicely maker marked and dated 'SMM43' indicating production in 1943. The aluminum cup is dated 1940. Nice original canteen in very good condition!
