Interesting, I did notice there seemed to be a US connection.
As far as I can tell - without actually picking up the phone and doing some proper research! - they closed definitively in 2005, after some years of struggling. There have been unsuccessful attempts to get the glass works going again. It certainly won't be happening in 2012, that's for sure.
I have a lamp in similar style which is unsigned and I have always thought it likely to be by the same maker. I'll put a pic up shortly for those who are interested.
Thanks to all.
