Antique Drinking Glass - Advice Needed

Hi all

So, this is something that I picked up recently. I have been starting to learn about antique drinking glasses, however it's very early days. This glass has all the hallmarks of age, the glass has imperfections and some small bubbles. The colour of the glass has a yellow tinge. The main body of the glass shows clear waves or ribs where it has been blown. It is a little wonky, so clearly hand made. And the foot is stepped.

Unfortunately what I have no idea about is age. Are there any drinking glass experts out there who may be able to shed some light?

Thanks as always.
