Help to ID some 1950's Philips wall lights/sconces  

Hello All,
I was wondering if anybody might be able to identify the designer of these Philips wall lights I bought just last week, they measure approx 27cm high. I've never seen them before and would imagine the survival rate to be quite low due to the fragile nature of the shades, I'm inclined to think they're very early 50's or possibly even late 40's...hoping somebody here will be able to enlighten me.
T.I.A.

Sorry about the pictures, I have resized them and tried to edit but it didn't work.
