Vintage Swirl-Ribbed Glass Soda Bottle

This is a vintage beverage bottle, likely a soda or mineral water container, characterized by a distinct spiral or 'swirl' ribbing design on the body. The bottle is constructed from clear glass, which has developed a significant translucent patina and interior 'sick glass' cloudiness from burial or long-term exposure to the elements. Its shape features a long neck leading to a crown-top finish, though the rim appears roughly chipped or damaged. The body displays diagonal ribbing that ends just above the base, which is circular and appears to have a slight heel. Based on the construction and the crown-top style, this piece likely dates to the early-to-mid 20th century (approx. 1920s-1940s). The condition is poor to fair, showing heavy surface dirt, internal calcification, and significant damage to the glass at the mouth. No specific maker's marks are clearly visible through the heavy surface grime, but the swirl pattern was a common design for regional soft drink companies attempting to differentiate their products from competitors during that era.
