Fristho Rudolf Bernd Glatzel vs Aurora  

Hi everyone, 

I see on the  web a lot of Fristho cabinet designed by Rudolf Bernd Glatzel that seem strange to me...

Some examples :

I think that all these pieces of furniture are in reality a Belgian manufacture of the Aurora factory in Izegem (see photo of documentation from 1964), but all the dealers contacted confirm to me that they are indeed Fristho furniture ... but they are never signed or labeled

Does anyone know more, or have old documentation to confirm either version?

Regards, Nicolas
