Hi, I got this paperweight from an estate of a paperweight collector, but unfortunately, there is no label on it. It has cogwheel millefiori with tiny placed bubbles between them. The grouping is on a copper aventurine base. It seems to be a high quality paperweight, and I was thinking it could be Fratelli Toso, but I haven't found pictures of labeled Fratelli Toso pwts on the Internet with a similar base. Do any of you recognize the maker? Thanks so much for your help!
