Rare cerimonial wine glasses

I acquired what I was told to be, blue cobalt & gold inlay ceremonial wine glasses from 1944. My uncle had given them to me about five years ago, and had stated several times that he carried them through World War Two. The third photo shows a bubble that is only on one of the glasses. I was told this indicates that they were hand blown. I've searched Google, and E-bay for even one set close to similar and there is nothing.I have also spoken with few people who say the wine glasses are unheard of. Please help me find out what these are.
