Kriegsmarine 'Kriegsabzeichen für Minensuch-, U-Boot-Jagd und Sicherungsverbände' (minesweeper war badge). The badge is an early 'Buntmetall' version. Badge is showing great details and retains all of it's original finish, it is complete with a functional pin and catch. It has never been cleaned nor polished. The badge is maker marked with 'Fec. Otto Placzek Berlin, Ausf. Schwerin-Berlin'. Nice original badge in very good condition!
