Hello again all. Another Charity shop find. 5 Uranium Glasses. They are 4 3/4 inches - 120mm high and 2 5/8in - 67mm in diameter and 8 3/4in - 210mm circumference. As you can see they are Uranium. The ribs can only be felt on the inside, smooth outside. If anyone can ID them I would appreciate it. A few tips on where to start looking would help as well. I only have the internet for reference and the few sites I have are useful but if there are some the GMB can recommend it would help. I use the encyclopaedia on here and a few more I have seen on here. Thanks. Pete
