Vintage Binder Brothers 1/20 12K GF Grapes Pin

An interesting pin depicting a bunch of grapes with a stem.  The grapes are created from coiled wire and they are suspended at different heights to add dimension to the brooch.  The pin is marked BB in circles which is the mark for Binder Brothers and 1/20 12KGF.  Binder Bothers was a German company based out of New York, NY.  This dates the pin to approx. 1930-1940's. 

The pin is in nice vintage condition with the exception of some plating loss (see photo).  The loss actually looks less visible in real life but our camera picks up everything.
