Hello and welcome to the gmb!
I have not seen anything like this before, it does appear to be of reasonably good quality, from what I can tell from your pictures, I can see why you like it.
Unfortunately, there is a lot a can't tell from your pictures. I cannot see if the clear panels are cut or if they have merely been protected from an acid treatment to frost/satinate the rest of the body.
We like looking at bottoms here
- there is a lot we can tell from how the base of a piece is finished. We could do with a good clear image of the base. No markings doesn't matter, (although they do help a lot!).
How is the rim finished? Is it cut and polished,, or is it smooth and heat finished? Can we have a picture of that please?
Just one more little nag - we prefer images with plain backgrounds, please so that we can see just the glass!
Thank you for the trouble you have already taken to post the pictures directly to the board and for resizing them properly - that is much appreciated!
Looking forward to a few more images, so we can try to work this out for you. There are folk from all over the world here, I'm sure somebody will be able to help you. Sorry, I can't.
