salem brothers floor lamp with amethyst in finial

I bought a salem brothers floor lamp circa 1930's.  It has two pull chain socket holders.  I don't know if shade goes with lamp or simply just came with it.  It has brass tubing and the finial has a cut amethyst in center finial.  the lamp is in very good shape.  Underneath the base salem bros. ny is clearly marked.  There are two numbers I think they are 32 but that is all i can make out.  There is rust underneath base of lamp.  In the pictures it looks bent howevere it is not.  I have to replace one interior lamp socket because pull chain would go down and lamp would come on but when i released chain that socket would turn off.  When i went to change all the wiring was in bad shape so i replacing both interior sockets and and wiring.  I am keeping original socket holders and i have all the screws.  The only real difference will be pull chains when i am done and the interior lamp socket.  I cannot find any images or information about lamp on net.
