thanks Keith. I've had a good search looking for the shape really. It's not iridescent and feels I guess, to date design wise, from around 1885 ish a similar time to the Carneol piece. I thought it might be Harrach perhaps but I can't match the shape at all.
I need to get better pictures loaded but the swirl design is a nightmare to photograph. I've also 'lost' the base and rim pics somewhere on my new computer and can't find where they've gone so I can upload them...I wish I was more technically minded lol.
