This water bottle is in good used I would estimate it to be 1920's 1930's Based on its neck design this is based on a simple internet search because I am not a glass bottle expert. No cracks or chips. There are a few natural bubbles in the glass that were there from the Manufacturing process. The bubbles would suggest an old process of manufacturing which would lead Credence to the age I'm estimating it to be in the 20s or 30s. it does have hard water stains in and on it probably could be cleaned with a product like SLR or other lime cleaner. . I'm not going to clean it because that could considered part of the patina. This bottle could have many different uses depending on your imagination. you could use it as Home Decoration , Greenhouse Plant Terrarium, Coin Bank or Home Made Beverage making bottle. .
