Calling All Retro Fans: Can You Identify This?

I recently bought a light fixture that I am in love with.  (yes, i ended that sentence with a preposition.  i could have said, "with which i am in love", but that's awkward.  judge me if you must.)  Anyway, this lamp is so funky and cool.  I would really like to narrow down the age and perhaps the value, since much of the vintage stuff I buy goes in my Etsy shop to feed my addiction.  Oh, and help out the seekers of vintage goodies who are not willing or able to dig through other people's crap at 7:00 on Friday morning.

I digress.  Here is a pic of the aforementioned funky, gorgeous light fixture.

I KNOW!!  It is so lovely.

So back to the task at hand, identifying its age.  It is a hanging lamp, with three globes that have a sort of leaf shape.  When I bought it I thought it was plastic made to look like capiz shell, but after I got it home I determined it was not plastic.  I think it is actual capiz, though it might be glass.  Does anyone know how to tell?

Here's a close up.

Husband has a lot of experience with electrical things (a politician with a skill.  go figure.), so I showed him the sockets that hold the bulbs.  He said they could be anywhere from 1940's to 1980's, just based on what he could see in the picture (the actual lamp is upstairs.  i am downstairs.  again with the judging?)  The sockets appear to be ceramic.

Here's what the guts look like.

 

Each globe/leaf has a little door that opens, and you can pull the socket out to change the bulb.  Sometime in the next few days I plan to have Husband look at the actual piece and see if he can date it based on the wiring, etc.  I would love to hear from any of you who have a thought, and if you see something like it somewhere, please let me know.
