Vintage silver enamel brooch, 9 separate flower heads, deals Scandinavian NR/189

A vintage silver Scandinavian enamelled flower brooch, marked "S925", probably from the 1950s and possibly earlier.
There are 9 separate flower heads each with four petals and a silver wirework centre, the enamel colours are pink shading to red, orange and white shading to pink, the body of the brooch is silver wirework, typical of Scandinavian jewellery from the early 20th C to current times, no makers name which is a shame as it is well made. Early form of a safety "C" catch and silver pin.
Has been cleaned but not polished and so the silver is heavily toned and would deals benefit for further cleaning.
