The Numbers on the bottom are pattern or item numbers. Without maker marks one will have a extreamly hard time to make out date or manufacter of the items. They are wonderful looking vases and would easy fetch $25.00 a piece without marks, as long as no damage is present. As for date and orgins it would just be a guess. Looks very french Victorian in style, however this style has been repeated over and over through the years. Sorry without marks not much can be concluded.
