Unissued M31 medical canteen or 1L Labeflasche marked AW 39 in factory box

Stone mint and unissued M31 medical canteen or 1L Labeflasche complete with the original factory box as how these would be issued / delivered to the German army. The canteen is perfectly matching and nicely marked AW 39 which indicates production by a still unidentified manufacturer. Finding unissued canteens is extremely difficult, especially complete with the factory box. The factory box is nicely marked with the manufacturers mark A.W. A must have for the dedicated canteen collector from my own personal which would be simply impossible to upgrade.
