the sig looks similar to another weight on ebay.com so I think it is genuine. It seems she has been making glass since the 80's, and won an award of somesort in the 90's but there doesn't seem to be any more recent information on her really.
To be honest, until recently there was little information on lots of studio glass makers on the net and I had a hard time finding anything on studio glass makers in the UK, especially if they were no longer working with glass.
