Hi and welcome.
I don't know anything about your glass piece (not my area), sorry.
However, you've put a lot of links in here, only one works and the image is sideways on.
I'm sure one of our Moderators will sort the extra links out, but could we ask you not to put links in the title in future - perhaps; "Is this 19th century English?" would have given your readers a better idea of what to expect, and would attract the attention of somebody who does know this area of glass.
Also, would you be kind enough to only put one piece of glass in a thread. This keeps the discussions on track.
Thanks. :thup:
