No need to apologize for curiosity. That's why we all frequent (haunt) this site. Again, according to Carl Gable, SVCC was created in 1898 out of the reorganization of an earlier firm. It was a very big firm, the largest in Murano for a while, with branches in France and Czechoslovakia.
I did a little more digging and Rosa Barovier Mentasti in Venetian Glass writes that SVCC got out making crystal glass after WWII to focus on its other specialty, glass beads. She writes that in 1964 the managing director of SVCC, worried about the future of glass beads, wanted to get back into artistic glass and hired Poli. They produced "brilliantly coloured sommersi, elegant red or yellow pulegoso pieces with gold leaf, as well as objects in purely-coloured or regularly bubbled incalmo blown-glass." Mentasti writes that the firm was poorly organized in the marketing of artistic products. The only pieces I have seen from this period are the sommerso pieces, particularly in brown and green. Poli took with him to SVCC some very good maestri, and they may have stayed on with the firm producing their own designs.
I haven't found anything about when the firm ceased operations. From looking on the Net, the big miscinception seems to be that SVCC was Poli's company, and that he started it in 1963 or 1964.
Hope this answers some questions.
