Wehrmacht M31 Canteen and Cup (Feldflasche 31 und Trinkbecher). The standard issue M31 canteen was introduced on 23 March 1931. The felt cover and leather straps are all in overall good condition with normal traces of years of storage. The aluminum canteen, felt cover, leather straps and aluminum black-painted cup are all nicely maker marked and dated with 'O.H.W.38', indicating production in 1938. The canteen is in overall very good condition showing minimal traces of usage and age, see photos. Nice original early all matching pre-war canteen in very good condition!
