The Silver Squirrel has dated this piece to the 1940s.
I would date it to c1940-1950. It has been superbly designed being in the form of a champagne cork and is marked underneath CHAMPAGNE. It is in superb condition being free from dings splits holes and repairs. It measures approx. 1.25 inches (3.2cm) tall by the same across the top by almost 1 inch (2.2cm) across the base and weighs 26 grams. A top quality very unusual example.
