Late war M31 canteen marked AEMA 43 with enameled cup

Excellent late war produced M31 canteen in configuration with an enameled cup. This canteen comes in a very interesting and unusual but still matching configuration! The flask itself is the M31 pattern constructed out of aluminium and the cup is a typical late war steel enameled type based on the steel M42 pattern canteens. Both the cup and flask are marked AEMA which indicates production by Annweiler Email-u.Metall-Werke in 1943. This is the first time I have ever seen this combination and this is for sure a rare and interesting canteen!
