I'm a retired guy who has a small one man shop specializing in restoring the old copper/brass fire extinguishers. I travel countrywide to purchase in quantity the best examples of these now obsolete firefighting pieces. Each is polished, lacquered, brass labels hand painted (if so desired) in various color combinations, soda-acid models have detailed cage, reproduction glass acid bottle and lead stopple, foam models have inner chamber (when available.) Metal polishing is a family trade going back to my grandfather in the 1920's. My customers are primarily firefighters, collectors, firefighting museums, individuals wanting to accent their home or office, and those wanting to give a gift for a holiday, birthday, or retirement.
