Hi, the glass looks like a Georgian (c1760) multi spiral opaque twist wine glass with bell bowl. The only thing that worries me is that the foot doesn't look right, but it could just be the angle of the photo. Can you post a photo from side on and of the underside of the foot? (If you don't know how then just save you photos to your computer, right click on the image (if using MS) and open with paint. Go to the "Resize and skew" option at the top left, click on pixels, change the "horizontal" to 500 and save as a .jpeg.) Kind regards, Neil
