Thanks mart! I thought something perhaps for a table setting and silverware, that was one of my guesses but I was not sure. A few say 24 % PBO Genuine Lead Crystall Western Germany, some others say 24% Echt Blie - kristall hochglanzpoliert Annahutte Western Germany. The "tt" in "annahutte" could be "ff" hard to make out. They are in excellent condition, probably used once if at all. As for age I'm not sure, perhaps vintage 60's or 70's?
