Two silver French continental brooches ring O roses and retailer Kelt

The large brooch is French Breton nationalism item possibly as early as 1930. White metal, stamped KELT and tests as solid silver. All symbols of the Breton region. Early trombone fastener. In excellent condition.
Other brooch is stamped france and also tests solid silver. Four children dancing as in ring O roses. Early trombone fastening pin. It has a swan neck. Works perfectly. I can't tell if that's retailer the original pin shape! Lovely pair of vintage continental silver brooches. From same collector.
