Hi,
Please,does anyone know which Italian pressed glass manufacturer used the letters SF in a five-pointed star, on the base of their productions? The image I have seen of the mark is less than clear, (ebay item number 330192962526) so the F could be a P. Looking around the net, some suggestions are that this mark is a variant for Fidenza Vetraria Sp.A. who are identified as also using a star with FV in the star, and both marks are found on a pattern of insulator known to have been made by Fidenza Vetraria. Can anyone confirm that it is the case that both marks were used, please?
TIA,
Marcus
