Pre war M31 canteen marked MN 38 with green painted cup

Excellent pre war canteen with factory repainted green cup in good used condition. The cup has been factory painted green over the black paint, issued at a later point than production when other regulations were in effect. The aluminium flask and the green painted cup are both nicely marked MN 38 which indicates production by Menesa Metallindustrie GmbH. Neunkirchen-Saar in 1938. The canteen features some very interesting unit markings which are rare to find on canteens, nice for a further research!
