Thanks for taking a look Ivo. It was purchased as having some age rather than being produced from recycled glass, so would be a little disappointing if this is the case, particularly, as it was purchased in good faith and from someone I have purchased from before. I was fairly sure, at least I thought, that the wear to the base was genuine and that it was at least Victorian in date. Perhaps the photos aren't the best, given the light. Although relatively inexpensive, I think I will return for a refund, if it is as you surmise.
