Unissued M31 canteen marked S.S.L. 39

Unissued pre war M31 canteen marked S.S.L. 39 (most probably) indicating production by Sieper & Sohne, Lüdenscheid. The canteen is a unissued example that would be impossible to upgrade. The canteen still retains the paper around the lid and has never contained any liquids. If you’re after one perfect canteen; this is it.
