An Unusual Bronze Grade Close Combat Clasp by Friedrich Linden, Lüdenscheid

In bronzed feinzink, vaulted, marked "F.E.C. W.E. PEEKHAUS BERLIN" and maker marked F L L (for Friedrich Linden, Lüdenscheid), slightly vaulted, some parts of clasp not bronzed giving it unusual appearance, unlikely it was done in the factory; in very condition.
