ID art deco? lamp  

Hi all!   i am new on this site.  Totally a design addict..  🙂

Today i found this ceiling lamp on the street in the rain next to the garbage. 

Its not my style - i am more of a modern-retro-sixties-seventies designlover -  but it seemed like art-deco to me so i picked it up and took it home.

One chrome arm is loose, but overall its in quite good condition.  The 3 handpainted? glasses are in tact but some paint is damaged, the dark wooden base and knobs are looking great too.   

Does anybody knows anything about this lamp/style?   Google lens could't really help me. 

Is this the website to be, or better ask somewhere else? 

is it worth anything? Or should i just put it in the garbage again... 😉

Thanks in advance!
