ID Tapio Wirkkala chandelier- Idman Artek Airam Iittala  

Help me ID this Wirkkala chandelier with 6 lights.

I took a look to photos on internet but I didn't find this model.

The pentagon shaped ceiling base is made of metal sheet (painted in matt black) and measures 24 cm (side).

Each tubular lamp holder is made of painted aluminium (diameter 5 cm, 3 different lengths: 10, 16, 26 cm). The tubular socket is different from the model published in the Idman catalogue (and also different from the new reeditions by Airam or Artek), as the bottom part of each cylinder has a small disc with 6 holes.

I found a similar one, sold by Pamono (attributed to Venini?) with the glass lampshades designed by Wirkkala with the same socket (last picture).

Comes with 6 shaped bulbs designed by Wirkkala for Airam .

It was probably bought in the '70 but I don't know who was the manufacturer.

Thank you very much!
