M31 Waffen-SS matching mess kit by RZM 6/6/39

Rare and light worn Waffen-SS mess kit, still retaining 70% of its original green finish. Aluminum construction. Matching lid and cup, bot maker marked by RZM 6/6 dated 1939. Interesting is the aluminum tag attached on the side, maker marked by 'ESB', a know manufacturer for mess kits. It is my believe that RZM maker mark 6/6 indicates the production of ESB, hence the attached tag. A very rare and seldom seen mess kit, RZM marked!
