Need help identifying origin of pin/brooch.

[infoseeker1957]

I purchased this little beauty resale. The folks knew nothing about it. It is a lovely intricate floral piece with a makers plate on the back but I cannot make out the letters/symbols. Does anyone know the likely origin of this piece or whose work it might be? From the pin closure it looks pretty vintage. Thanks for your help.
