You clearly have a really good haul of Mdina glass!
Some excellent bits, and some more common.
This thread is already starting to get very confusing, with lots of different pieces.

We
can help you with your queries, but we like a single topic to be dedicated to each single piece of glass.
We also like images posted directly to the board - thank-you for doing this,

but they're sideways and they do not blow up big enough for use to be able to see them properly.

There is a lot of help and info in this link here, to help you to get the images sorted properly.
http://www.glassmessages.com/index.php/topic,34093.0.htmlThen can we ask you to start a new topic for each piece of glass, please?
Then we can get a moderator to remove all the extra images from this topic.
To make a mark or signature on glass stand out for photography, rub a little talcum poweder over it with your thumb.
We do need to see the bottoms of bits of glass.
