Unissued M31 canteen marked HRE 41

Excellent textbook M31 canteen in unissued, mint condition. The canteen is nicely marked HRE 41 which indicates production by Heinrich Ritter, Esslingen in 1941. The only flaw on this canteen is that the felt cover has some minimalistic moth damage. Excellent textbook M31 example which is a must have for every canteen collector!
