The name etched on it could either be the srtists first name or surname and could have originated from any art glass studio,. there are many glass makers the World over producing weights and art glass in both major and minor studios and even small private individuals in their own back yards and products from these may never be identified outside their own area unless they become 'discovered' and join a group of artists in a well known and established art glass studio so attempting to research them through the internet, unless they have their own site, may be fruitless, just take satisfaction that if a weight or piece of art glass has an individuals signature etched on it then they were proud enough of it to put their name on it and if you like it that makes at least two of you.
