No maker and no specific year, but I think we're safe to call this a 1970s Danish circular table lamp.
Indeed Danish is pretty much all that is attributed to it, with the seller adding that it is 'in the style of Fog & Morup, Poulsen and Lyfa' and 'possibly a design by Hans Agne Jakobsson'. Make your own mind up about all of that.
What we do know is that the light is made from spun aluminium layers under a glass globe. It's said to be in 'nice condition', with 'minor scratches' on the glass, but no cracks.
If you want it, bidding right now is at 62 pence. Plenty more images on the listing too.
