1950's Brass and Floral Glass/Crystal Candelabra Chandelier

I Believe this is a 1950's  a 6 light Candelabra Chandelier with Brass Canopy fixtures.

There are numbers 865, 866, 867,868,869 and 870  where the arm pieces join the base.  

There is a hallmark in between the connectiong arm pieces and the main stem piece, but I cant make it out.  My  friend said she thinks it may be a masonic hallmark?

I don't know if the pendalouges or bobeches are glass or crystal. I don't know how to tell the difference between the two.

The arms scroll in the shape of an "S"  with little flower pendalouges and beads attched to it.  

The candles are plastic and very fragile.

The Chain that connects to the stem is brass with designs engraved on the rings. 

I tried to take clear pictures to view for a better  more clear detailed description.  

Does anyone know who or where this was made or the value of it?

Thanks for your input.
