Hello and welcome.

Thanks for struggling with your image and posting it directly to the board - that is much appreciated.
We do have a lot of techie help and info here:-
https://www.glassmessages.com/index.php/topic,34093.0.htmlto help with resizing, so that images can be blown up properly from the thumbnail.
I suspect we might need to see more fine details to help you with this.

It's certainly the sort of thing I've only really seen in museums, I'm not sure how far we'll get with tracking down the maker, but I am sure we can have a lot of discussion about it.
You can attach 4 images to each post you make - just click on the bit under the "browse box" to get another one.
