I'm going crazy trying to figure out the marks of a double tastevin, the first one I come across and which from the decoration must be from the end of the 19th century, could it be pewter? I hadn't thought of that but I don't know where else to hit my head. if so, any suggestions on invoice country? 6G stands for?
