The white metal insignia (wreath, cabbage) for Wehrmacht peaked cap. It has 3 brass legs on the inside for attachment. There is also a Ges. Gesch. inscription on the inside (gesetzlich geschützt, literally: protected by law) - patent mark, used until 1945.
Usually the badge came with the same quality metal eagle, together they made a set of insignia for one cap.
Very high quality, made in Germany.
