I would estimate it was made in the early to mid 20th century. All have mercury glass liners to keep liquids cold or hot. This jug is about 9 3/4 inches tall and about 4 1/2 inches in diameter at the base.
It's total weight (including the glass liner) is about 1,000 grams. The jug has an attractive old-style'dolphin' finial on the lid. It is in very good condition with minor scratching and wear from polishing over time. No cracks in the glass liner.Please refer to photos and feel free to ask questions.
