Wehrmacht M31 Mess Kit (Kochgeschirr 31). The 'Kochgeschirr 31' was introduced on 23 March 1931. This is a nice original early war all aluminum construction mess kit. The mess kit is maker marked and dated with 'G.L.B. 36' and 'ZPSt. 38. The mess kit still retains most of its original fieldgrey paint. Nice original mess kit in used condition!
