These old fashioned fired extinguishers were made of copper, sometimes later ones were stainless steel, abd worked when you turned them upside down. Water was mixed with baking soda and a small bottle of acid (sulfuric maybe?) was put into a small bottle and held upright internally, then the top was screwed on and the extinguisher placed on a hook on the wall or in a glass front cabinet. If there was a fire, you took the extinguisher and turned it upside down, the water/soda mixture mixed with the acid and developed instant pressure (like vinegar and baking soda) that forced the water out in a stream. The process continued until the extinguisher was empty. They were outlawed in about 1972. Replaced by dry chemical extinguishers.
