Hi Nige,
I really, really love your Greta lamp but as Im collecting mainly blue Walther glass (some green recently) I will wait and hopefully one day you will have one in either colour. I notice you often have lovely pieces to swap but unfortunately I certainly wouldnt have anything that you would want - I started collecting glass rather haphazardly only a few years ago but after meeting a local lady with a lovely Walther collection I was hooked!
Kind Regards,
Aline
