Antique glass acid bottle originally designed for use inside a soda-acid fire extinguisher. The bottle features an embossed “ACID LINE” marking around the center and retains its unusual heavy original-style closure/stopple.
These internal bottles held the acid component separately within early fire extinguishers, making this an interesting piece of vintage firefighting and industrial history.
