Welcome.

You've found the right place, but I'm afraid we do need to see your bit of glass properly.
Thanks for having a very good go at posting your images to the board, but they don't blow up to be very big. We do have a whole load of techie tips and info here,
http://www.glassmessages.com/index.php/topic,34093.0.htmlwhich might help you to resize your images a little bit better. Your current images do not blow up big enough to see any detail.

A signature or factory mark can be brought up by giving it a little dusting of talcum powder and rubbing the excess off with your thumb - failing talc, flour could be used (but it can go gummy when wet, it's more of a pain.)
We like looking at bottoms here, we always want an image of the base. Even if it doesn't look as if there's anything there, the
sort of finish can tell us a lot.

I'm sure somebody will be able to help you identify this - is there a signature there?
