Set of 4 Silver Kiddush, Aperitif, Cordial or Wine Glasses

Shiney, Streamlined almost Art Deco and appear to be silver plated. They are made in India and stamped. I cannot make out the stamp. It is pictured so maybe someone can tell me. Silverplate? Sterling? They are 5.5” tall. There is some signs of tarnish as pictured but they polish beautifully. They were brough over from Israel in the early 1990’s.
