Animals can be the most difficult pieces of glass to attribute if they are not signed. Your elephant does not look like the standard BT elephants, which were made with 4 legs using various techniques and decorations. Sometimes the best we can do for unknown animals is call them Murano or Murano-style if we think it is what they look like. Elephants sell poorly on eBay if they do not have an attribution. If you feel your elephant is a good one, it may be good to look around the web to see if you can find one like it that has a label. I look at a lot of animals, so I know it is a difficult task! I suspect from the decoration that your elephant is Italian glass, probably Murano. It appears to be large, which is good. The decoration looks like decoration I have seen for a couple of companies, but I don't particularly associate it with BT.
