This is a standard Wehrmacht 'Fettbuchse' (Butter Dish or Fat-Container). These containers rank among the 'basic' equipment of any front-soldier and were stored in the bread-bag. The dark-brown/black coloured bakelite container is in good condition and fully functional. Example opens in 1/4 turn like it should be. The container is showing some normal traces of usage. Nice original example in good used condition!
