Unnamed cups

These Beautiful Cups or Wine silver tin glasses, were given to me by my grand uncle as a gift in 2006. He said he had bought these items from an antique store in Cairns a very long time ago. He didn't even know what was in the blue box nor did the lady in the store tell him what was in the box. He had asked the lady in the store to wrap it, which the lady wrapped it in Newspaper and used tape. It has been in his cupboard wrapped up in that newspaper since the time he bought it. He cant remember when he bought it and what was in them. My Grand uncle brought them over to NZ from Australia and gave them to me as a gift, I unwrapped this gift and to my surprise opened the blue box and saw these beautiful cups. I still don't know what these are. But I do use it for drinking my port from time to time. Please help, I only know they are cups and wine glasses but not its original name.
