Rare M31 messkit marked ESB 31

Rare M31 messkit marked ESB 31 and VDNS35 and named Gehr on the lid. This is a very hard to find, first year of production and testing for the German army. The messkit has lost most of its factory paint. Finding pre 1935 examples is exceedingly hard as most if not all of them were used up during the following war. Rare opportunity to acquire a genuine 1931 dated example!
