Vintage West German Scarf Clip or Brooch Converter

This is a vintage gold-toned costume jewelry accessory, identified by its oval shape and mechanical fastening system. The piece is constructed from a non-precious base metal with a bright gold-plated finish. Centrally, the item features a hinged, circular tension ring designed to hold fabric or convert a brooch into a scarf slide. The reverse side clearly displays a stamped hallmark reading 'WEST GERMANY', which dates the item's manufacture to the period between 1949 and 1990. The construction shows a decorative scalloped or filigree-style edge visible around the perimeter of the central plate. In terms of condition, the gold plating appears well-preserved with minor surface scratches and slight oxidation consistent with age. The mechanical hinge and tension loop seem intact and functional. The style is representative of mid-to-late 20th-century European costume jewelry production, known for durable plating and functional designs. The craftsmanship is typical of high-volume West German manufacturing, characterized by clean stamping and sturdy assembly.
