Yes I've discussed this with thewingedsphinx (Mike) and he thinks not northeast. I bought it on the off chance it was Thomas Kidd. Having examined it, I think the glass is a bit too thick and solid for Kidd. Although it was the right density for them, around 2.5g/cc, I'd need to see one in colour to up the likelihood of them being the maker, I'm currently at 10-20%. This leaves few other possibilities at that density range in 1897, and so I'm turning thoughts to someone like Defries, or a commission from a London agent for the Jubilee.
