This model is attributed to Robert Sonneman and was produced through the 1970's and 80's.

This is an earlier model with single light fitting and power cable exiting from the vertical tube, rather than the base. 

The lamp is 45cm tall, the diameter of the shade 32cm

I've owned this from new and it was in daily use until a couple of weeks ago, when i decided it was time for a change! 

The chrome finish is in excellent condition, with just a couple of minor blemishes on the top of the shade. The painted underside of the shade is also in excellent condition. 

Ideally would prefer that the item is collected, but will post if necessary.
