Lacquer and Eggshell modernist box. Paul Emile Brandt

An extremely hard to find lacquer and eggshell box attributed to Paul Brandt.
Not sure about metal. Silver gilt ? Maker hallmark (RSA and anchor) . Stamped "MADE IN FRANCE". Numbered.
Unsigned, as often for Paul Brandt boxes.
But pattern and colors are typical of this artist.
86mm 80mm

Circa 1930.
