Hi, Having carried out further research based on the information gathered, I would say that the paperweight posted is not Langham Glass, as I initially thought. Langham Glass are normally signed. My piece is more likely to be Chinese. The one posted on Ebay is also likely to be Chinese, unless there is a valid signature on the base to prove otherwise. It is also possible, that some pieces slip through the net without signatures after being made. I have not contacted the Seller, as I am happy to label mine as Chinese................then again, I could be wrong about that too!
. Anyway, thanks for your information, as this has helped to determine mine.
